Hi Maverick,
The website is hosted on a domain using PHP 7.2 using CjForum 2.2. In the error log of the domain I find numerous lines like the following:
Backend log: PHP Warning: count(): Parameter must be an array or an object that implements Countable in /home/.../domains/.../public_html/components/com_cjforum/models/categories.php on line 51n, referer: https://..../forum/...
Backend log: PHP Notice: Undefined index: created_by in /home/.../domains/.../public_html/administrator/components/com_cjforum/models/topic.php on line 523n, referer: https://..../forum/?view=form.....
What do they mean please?
