Hi,
I had a look.
Your current issue is caused by WP Cerber plugin. Here is what is happening:-

1. On ‘init’ action, wp cerber check for access and if the url is prohibited, It loads 404 page.
The problem is, It is loading theme’s header.php too early(normally, It should do that at ‘wp’ or below).

At ‘init’ action, BuddyPress components are also setup and since WP Cerber has slightly high priority, it loads the page before our MediaPress gallery component is setup.

MediaPress plugin hooks to ‘body_class’ to add some extra css classes to ‘body’ element. On the 404 page created by Cerber, this gets called too early(before even having the component setup). That is causing the issue(the slug is not defined at that time).

The real solution would be to have W Cerber fix it by loading the template late(I checked their wp.org page and It is under temporary suspension currently, so could not request them for it).

A temporary fix form our side will be to add an extra check for MPP_GALLERY_SLUG being defined(we should not need to do it as our plugin guarantees it to be defined at init).

I will push a release tomorrow to fix this one for you.

Hi Vladi,
Thank you for the reply.
All servers are different and there may be some issues with configuration. The current version of MediaPress has been a very stable one but I am expecting some issues with PHP 8.0+ to surface.

If there is a critical error notice, It is some fatal error and the only way to know it will be if you share the error log(php error log). If you can provide that for audio, we can check and update the plugin with the same.

In the meantime, for the current issue, Please share the following details:-

1. Your current php version
2. Are you using WordPress multisite? If yes, Is MediaPress network active?
3. Are you using it with BuddyPress?
4. If yes, which version of BuddyPress/WordPress are you using?
5. If yes(3rd), is the error happening on profile or group page?

6. If no, is the error happening on upload or viewing?

Thank you

Hi Vladi,
Welcome to BuddyDev foums.
I am sorry for the inconvenience.
I am not sure what is causing it. It seems some code is causing this function mpp_is_component_gallery() too early.

We are defining that constant in mpp_setup_core which should be fine.

is there any recent changes on your site? Are you using any custom code related to mediapress? Please share and I will assist.
