i get an error from the "access" plugin:

Fatal error: Uncaught Error: Class 'OTGS\Toolset\Access\Controllers\CustomErrors' not found in /home/customer/www/app.com-unity.co.il/public_html/wp-content/plugins/types-access/application/models/wpml_settings.php:400 Stack trace: #0 /home/customer/www/app.com-unity.co.il/public_html/wp-includes/class-wp-hook.php(287): OTGS\Toolset\Access\Models\WPMLSettings->check_language_edit_permissions(Array, Array) #1 /home/customer/www/app.com-unity.co.il/public_html/wp-includes/plugin.php(206): WP_Hook->apply_filters(Array, Array) #2 /home/customer/www/app.com-unity.co.il/public_html/wp-content/plugins/sitepress-multilingual-cms/sitepress.class.php(2798): apply_filters('wpml_active_lan...', Array, Array) #3 /home/customer/www/app.com-unity.co.il/public_html/wp-content/plugins/sitepress-multilingual-cms/inc/template-functions.php(110): SitePress->get_ls_languages(Array) #4 /home/customer/www/app.com-unity.co.il/public_html/wp-content/themes/Avada/includes/lib/inc/class-fusion-multilingual.php(225): icl_get_languages('skip_missing= in /home/customer/www/app.com-unity.co.il/public_html/wp-content/plugins/types-access/application/models/wpml_settings.php on line 400

once i turn it off - the site is ok. but I have to have the plugin on.

When I use 2020 theme - it's ok, too. but with avada (not even the child theme) - it goes wrong again.

everything is updated no the site.

any ideas?

Can you please share FTP access details as I would like to apply the hotfix shared by our devs to see if it works.

*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.

I have set the next reply to private which means only you and I have access to it.

Unfortunately - admin access details is not working but FTP does.

So, I've applied the patch file, do you see that fix the issue. Can you please confirm?


My issue is resolved now. Thank you!
