the reason i bought this is because of republish features that work with payment pro plugin

Please help
Thanks

also when publish new item it used my credit which i thought that it wouldn't

I used AAM to renew ads just fine, I got this plugins thinking I can have "pay to republish" but it doesn't work. Can you guide me to make it work please. I would like to push my site live if I settle this last hurdle. Thank you.

Where did you get that Backoffice Manager Plugin works with Osclass Payments Pro ?

Your words

@ysalim
That is correct, you have asked if Zara theme works good with Osclass Payment Pro.
And that is correct, it works.

However there was no question regarding Backoffice Manager and Osclass Payment Pro plugin. "Paid republish" works only with Payment Plugin (free one).
If we would use paid Payment plugin (osclass pro or some else), it would means:
"If you buy Backoffice Manager Plugin, to get all it's functions working, you need to buy another plugin"
... this is not acceptable

"This is not Acceptable" ??    I am not here to start an argumentation, I just saying that I didn't know the feature only works with a free payment plugin until I bought and tested it. I was under impression that if the answer is "yes, we don't have any evidence that it has a problem with payment pro " then
I had an expectation that all features work well with payment pro plugins without restrictions. Not like "It works well but it doesn't do the other thing".  Frankly, The pay to republish is one of the features that made my buying decisions.  I am not asking for anything right now, just hope that the communications are a little bit clearer so that we don't have misunderstanding.

@ysalim
1) On demo in oc-admin you have:
"Pay per post" option in Payment Plugin is not allowed or Payment Plugin is not installed. You need to enable first this to be able to use "Pay for republish"
2) On product page (http://mb-themes.com/home/17-backoffice-manager-plugin.html) you have:
set paid republishing (in cooperation with Payment Plugin that manage payments)

No complains are acceptable here.
