Hello Calin, done!
Thank you,
Paolo

Thank you Calin, it works perfectly!

Hi Calin, these error messages actually appeared (and continue to appear…) only after updating to the latest version (5.1) of Newsmag and without loading new plugins.

The problem is that they are many and of different types, for example:

Fatal error: require_once(): Failed opening required 'ABSPATHwp-admin/includes/class-walker-category-checklist.php' (include_path='.:/opt/cpanel/ea-php74/root/usr/share/pear') in /home/travelan/public_html/wp-admin/includes/template.php on line 12

or:

Fatal error: Uncaught Error: Class 'WP_List_Table' not found in /home/travelan/public_html/wp-admin/includes/class-wp-plugins-list-table.php:18

Stack Trace
1.
{main}
thrown in /home/travelan/public_html/wp-admin/includes/class-wp-plugins-list-table.php on line 18

and again:

Fatal error: Uncaught Error: Class 'WP_Upgrader' not found in /home/travelan/public_html/wp-admin/includes/class-theme-upgrader.php:21

Stack Trace
1.
{main}
thrown in /home/travelan/public_html/wp-admin/includes/class-theme-upgrader.php on line 21

or:

atal error: Uncaught Error: Class 'WP_Filesystem_Base' not found in /home/travelan/public_html/wp-admin/includes/class-wp-filesystem-ssh2.php:36

Stack Trace
1.
{main}
thrown in /home/travelan/public_html/wp-admin/includes/class-wp-filesystem-ssh2.php on line 36

We can’t figure out if it depends on WordPress or the theme. Since it’s a magazine and we wouldn’t want to have any problems, in case you guys could work to fix it for a fee?

Thanks!

Thank you Calin!
The customizations were done directly by TagDiv team (I think Bogdan did them), adding the custom field “post_views_count” in order to be able to realign the number of views after migration.
I don’t know if it was done in the child theme or not…
Is there any way to verify this before updating the theme?

Thanks again!
