Some from debug log.

Osclass 5.1.2 and PHP 7.4.x NO PLUGINS.

That is about it, finished my research with Osclass.

The carousel:

The latest ads posted:

Shopclass appears 3 times in admin dashboard. One at the end of the menu as Shopclass standalone menu, one in Themes and one in the Dashboard.

I think it is either some bug or toooo much,

Not sure what this is, i have never seen that before trying Shopclass theme for a few days.

Missing information for Alerts in user Profile:

A small typo mistake:

"Forgot your" is the correct text (instead of Forget You). And maybe the Reset here, should be Reset it here.

If Permalinks are not enabled as friendly, Report an Ad goes to 404.

Some non-english sites do not enable friendly slubs because of issues with high-bit characters.

Reporting with Bender and other themes works right.

TinyMCE doesn't work anywhere. While enabled.

In both user and admin edit:

It shows nothing at all, empty space with:

admin edit:

The resource from “https : // website . com/oc-admin//themes/silver/themeundefined.js” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff) in index.php

and in user:

The resource from “https:www . jsksks . com//home/oc-includes/assets/tinymce/themes/modern/theme.min.js” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff)

Not compatible with PHP 8. Many depreciated messages.

It seems the legacy Youtube plugin doesn't work with Shopclass theme.

Osclass 5 dev latest. PHP 7.4

This came from a friend and i verified it, happens at your site also.

With FIREFOX browser in Tablets and Cellphones. In SOME categories when Gallery view is selected.

I made a video, to see and maybe fix.

tfcAdsLoop.php

There is an unclosed div here:

<li> <div class="nav-link"> <i class="fa fa-clock-o text-danger"></i><?php echo $item[ 'itemPublicationDate' ]; ?> </li>

When you delete a user with ads, you get "No users have been deleted" and the ads become empty (but there).

You must then delete the ads and then the user.

Also several "foreach" php warnings.

data-vocabulary.org schema deprecated

A lot of messages can't be translated, either because they are in the php code (like question marks, some "close" or ":"), or because the are not linked with the messages (like in the public user profile).

Everywhere that excerpt is shown, at the end of line there are html codes like

&omic...
&o...
&tau...
&s...
&la...
&sigmaf...

and others.

When hovering the main photo (without clicking), instead of "click image to zoom" i get the image alt title appearing on random areas in the LEFT:

Also in the item page, with ONE photo, hovering to the right of the main photo i see some "image 1/1":

Strangly enough i don't see those issues at your tuff* site. I run Osclass 5.2.dev and PHP 7.4.x.
