I've researched and found that clearing bookmark_ui table might help but looking through PHPmyAdmin I can't even find the table.

I added an attribute to the columns 'free shipping' and it seems to have started since then, but unsure.

All the columns are visible but only a couple are selected - they shouldn't all be visible.enter image description here

This ended up being a faulty third party plugin issue which was resolved by them updating their code.

This happened to me once and it ended up either being an issue with max_execution_time. Flush cache and reindex first to confirm that the issue isn't there and then try this:

  1. Locate your php.ini using a phpinfo.php file.
  2. As a user with root privileges, open php.ini in a text editor.
  3. Locate the max_execution_time setting.
  4. Change its value to 18000 (or 36000 if it is already 18000).
  5. Save your changes to php.ini and exit the text editor.
  6. Restart Apache:

    CentOS: service httpd restart

    Ubuntu: service apache2 restart
