Hello,

I start use Forum plugin, but isn't work well. When i try remove created forum category it show error:

Fatal error: Uncaught TypeError: count(): Argument #1 ($var) must be of type Countable|array, bool given in /public_html/oc-content/plugins/forums/model/ModelFRM.php:963 Stack trace: #0 /public_html/oc-content/plugins/forums/admin/category.php(35): ModelFRM->removeCategory() #1 /public_html/oc-admin/themes/omega/plugins/view.php(38): require_once('...') #2 /public_html/oc-includes/osclass/helpers/hDefines.php(232): require('...') #3 /public_html/oc-admin/plugins.php(704): osc_current_admin_theme_path() #4 /public_html/oc-admin/plugins.php(434): CAdminPlugins->doView() #5 /public_html/oc-admin/index.php(140): CAdminPlugins->doModel() #6 {main} thrown in /public_html/oc-content/plugins/forums/model/ModelFRM.php on line 963

Same problem when i try delete a buard:

Fatal error: Uncaught TypeError: count(): Argument #1 ($var) must be of type Countable|array, bool given in /public_html/oc-content/plugins/forums/model/ModelFRM.php:980 Stack trace: #0 /public_html/oc-content/plugins/forums/admin/board.php(57): ModelFRM->removeBoard() #1 /public_html/oc-admin/themes/omega/plugins/view.php(38): require_once('...') #2 /public_html/oc-includes/osclass/helpers/hDefines.php(232): require('...') #3 /public_html/oc-admin/plugins.php(704): osc_current_admin_theme_path() #4 /public_html/oc-admin/plugins.php(434): CAdminPlugins->doView() #5 /public_html/oc-admin/index.php(140): CAdminPlugins->doModel() #6 {main} thrown in /public_html/oc-content/plugins/forums/model/ModelFRM.php on line 980

Correction in model:
  if(count($boards > 0)) {

into:
  if(is_array($boards) && count($boards) > 0) {

then:
  if(count($topics > 0)) {

into:
  if(is_array($topcis) && count($topics) > 0) {

Thanks for feedback, will be fixed in latest version as well
