Hi cool_recep,
Regarding the warning, if you go to that file, line 488, you will see this:
Code:
$buf .= $this->display_config_row(_('Enablle LiteSpeed Cache', 'litespeed-cache'), $input_enable);
This should be edited to:
Code:
$buf .= $this->display_config_row(__('Enable LiteSpeed Cache', 'litespeed-cache'), $input_enable);
(There should be an extra underscore, Enable is also a typo)
Regarding the admin bar issue, we do not have the wiki up yet, but essentially, you need to add the following line to your .htaccess file for both XenForo and WordPress,
after RewriteBase and before any rules with the [L] flag:
Code:
RewriteRule .? - [E=Cache-Vary:_my_custom_vary]
As lauren explained earlier, they are using the same cookie. You should have a different value for each web application, _my_custom_vary is just an example. One example is something like _my_wordpress_vary and _my_xenforo_vary. Whatever they may be, it should be different for each web application installation.
Once those are added, update your LSWS installation to the latest 5.0.14. It was patched with this fix.
Let me know how it goes,
Kevin
