@MWINDEY
thanks both will be fixed in next update.

@MB Themes,

Super, looking forward to it.... Thanks for this great plugin it is magnificent 

@MB Themes,

Updated but still not possible to delete auctions in admin area by clicking the garbage can. The page renews but it is not deleting item.

Well you cannot het update that is not yet released 

Well ok...I thought it was an update i did fom 1.0.4 to 1.0.5 at that time but nevermind  ...
I do have one suggestion... While you are working on the update, is it also possible to place a link in the active classifieds to start an auction or is this rather template dependent?

For epsilon i created the link in user-items page to start the auction from there...probably works on other themes also
<?php if (function_exists('act_header_link_hook')) { ?>
<form class="act-form nocsrf" method="POST" name="act-form" action="" enctype="multipart/form-data">
    <input type="hidden" name="action" value="createauction">
    <input type="hidden" name="actItemId" id="actItemId" value="<?php echo osc_item_id(); ?>">
<button type="button" class="act-btn act-btn-primary" onclick="confirmStartAuction(this)">Start auction</button>
</form>
<script>
function confirmStartAuction(button) {
    var confirmation = confirm("If you proceed, the auction will start immediately and become active. You are required to adjust the auction settings immediately after starting. Note: You are obligated to sell the item to the highest bidder. Are you sure you want to proceed?");
    if (confirmation) {
        startAuction(button);
    } else {
        alert("Auction has been canceled");
    }
}
function startAuction(button) {
    var itemId = button.parentElement.querySelector("#actItemId").value;
    if (itemId !== "") {
        window.location.href = "<?php echo osc_route_url('act-create-item-auction', array('createItemId' => '')); ?>" + itemId;
    }
}
</script>
<?php } ?>


@mwindey
We do not have hook for buttons on user items.
Besides that you should also check if auction is eligible for start

Ok so i ceated a hook and when starting an auction it points to auction-edit page so that if osclass pay is required before activation it does not start.
Same as on the auction page itself.... Button to select/deselect in admin area was added.

Few steps to follow and it works.

step1: In user-items.php from THEME find:

<a class="delete" onclick="return confirm('<?php echo osc_esc_js(__('Are you sure you want to delete this listing? This action cannot be undone.', 'epsilon')); ?>')" href="<?php echo osc_item_delete_url(); ?>"><i class="fas fa-trash"></i> <?php _e('Delete', 'epsilon'); ?></a>
Underneath add:

<div class="auction">
<script>
    function startAuctionFromItemPage(itemId) {
        var firstConfirmation = confirm(<?php echo json_encode(__('If you proceed, the auction will start immediately and become active. You are required to adjust the auction settings immediately after starting. Note: You are obligated to sell the item to the highest bidder. Are you sure you want to proceed?', 'epsilon')); ?>);

        if (firstConfirmation) {
            var secondConfirmation = confirm(<?php echo json_encode(__('IMPORTANT: Please do not forget to set the duration and price for your auction after clicking on \'Proceed\', otherwise the auction will become active and will be offered at the lowest price. Are you sure you want to proceed?', 'epsilon')); ?>);

            if (secondConfirmation) {
                startAuction(itemId);
            } else {
                alert(<?php echo json_encode(__('Auction has been canceled', 'epsilon')); ?>);
            }
        } else {
            alert(<?php echo json_encode(__('Auction has been canceled', 'epsilon')); ?>);
        }
    }

    function startAuction(itemId) {
        if (itemId !== "") {
            window.location.href = <?php echo json_encode(osc_route_url('act-create-item-auction', array('createItemId' => ''))); ?> + itemId;
        }
    }
</script>

<?php 
    if (function_exists('act_item_link_hook') && act_item_link_hook() == 1) { 
        osc_add_hook('item_links', 'act_item_link_hook');
    } 
?>
</div>

step2 THEME CSS / file style.css search for:  USER ITEMS and underneath add:

.start-auction-btn { padding: 6px 8px; margin: 6px 6px 0 0; border-radius: 6px; background: #00bdd6; color: #fff; font-size: 13px; font-weight: 600; line-height: 1.2; box-shadow: 0 0 0 1px rgb(59 73 223 / 30%) inset; text-decoration: none; cursor: pointer; transition: background 0.2s, color 0.2s;}
.start-auction-btn:hover { background: #2f3ab2; color: #fff;}

Step3: SELECT PLUGIN AUCTION MAP / index.php from AUCTION plugin find:

osc_set_preference('hook_header_links', 1, 'plugin-auction', 'BOOLEAN');
Underneath that line add:
osc_set_preference('hook_item_links', 1, 'plugin-auction', 'BOOLEAN');

Step4: In functions.php from plugin find:

osc_add_hook('header_links', 'act_header_link_hook');

Underneath add:
// ADD AUCTION LINK IN USER ITEMS
function act_item_link_hook() {
  if(act_param('hook_item_links') == 1) {
     echo '<button type="button" class="start-auction-btn act" onclick="startAuctionFromItemPage(' . osc_item_id() . ')">' . __('Start Auction', 'auction') . '</button>';
  }
}

Step5: in admin/configure.php  from  AUCTION plugin find:

$hook_header_links = mb_param_update('hook_header_links', 'plugin_action', 'check', 'plugin-auction');

Underneath that line add:

$hook_item_links = mb_param_update('hook_item_links', 'plugin_action', 'check', 'plugin-auction');

In the same file find:

        <div class="mb-row">
          <label for="hook_header_links" class=""><span><?php _e('Add Auctions Button to Header', 'auction'); ?></span></label>
          <input name="hook_header_links" id="hook_header_links" type="checkbox" class="element-slide" <?php echo ($hook_header_links == 1 ? 'checked' : ''); ?> />
         
          <div class="mb-explain">
            <div class="mb-line"><?php _e('When enabled, button to search page with auctions only is added to header. Require Osclass Hooks 8.2 support.', 'auction'); ?></div>
          </div>
        </div>
       
       
        <hr/>

Underneath that line add:

        <div class="mb-row">
          <label for="hook_item_links" class=""><span><?php _e('Add Auctions Button to User items', 'auction'); ?></span></label>
          <input name="hook_item_links" id="hook_item_links" type="checkbox" class="element-slide" <?php echo ($hook_item_links == 1 ? 'checked' : ''); ?> />
         
          <div class="mb-explain">
            <div class="mb-line"><?php _e('When enabled, button to initialize auction is added to user active items. Require Osclass Hooks 8.2 support.', 'auction'); ?></div>
          </div>
        </div>
       
       
        <hr/>

Your done 

Cool 

@MB Themes

I also added the delete option in admin and looks like this is the solution...Tested and works for me.... Can you please double check this?
complete file admin/auction_edit

Same issue with not being able to delete item from hot auction list after finished. I am assuming some updates are still in the works for this plugin.

@Sparky,

If you Change the file to my solution it works perfectly.
<?php

    if($deleteId > 0) {
        // Call deleteAuction function with the deleteId as argument
        $result = $modelACT->deleteAuction($deleteId);
        
        if($result) {
            // Add success message if auction is successfully deleted
            osc_add_flash_ok_message(__('Auction successfully deleted.', 'auction'), 'admin');

When can we expect an update @MB.

Thank you @mwindey , but I will wait for an update.
