I'm aware of the requirements document at https://downloads.joomla.org/technical-requirements. But that doesn't define which PHP extensions are required to run Joomla without getting the red screen.

[PhilTaylor-Prazgod]

The requirements have been the same for almost 2 decades now.

They are the same as listed for Joomla 3 on https://downloads.joomla.org/technical-requirements

Zlib Compression Support, XML Support, INI Parser Support, JSON Support, MB Language = Default

Any decent mainstream webhost should already have these extensions installed. This is not rocket science - this is basic PHP and nothing special about this list

Joomla 4 has some OPTIONAL requirements also documented here: https://docs.joomla.org/J4.x:Optional_T ... quirements

I got this red image page in Joomla 4 after installing T3 plugin. Maybe this wasn't correct file t3-2.7.7.zip
The help on red page didn't help me by changing this $debug = false; to true
Now I can't open administration to disable this plugin
What to do, please help

Code: Select all

[Beata]

Finally after changing permission I got this but what to do with this ?

[ceford]

Use phpMyAdmin to find that plugin in the extensions table and set its enabled value to 0.

[Beata]

Please more exactly...
Should I go to MySql?
Or maybe I can delete that plugin through FTP?

P.S. I am in mySql and don't know how to find this table....

[ceford]

Everybody uses phpMyAdmin to interact with MySQL databases - you hosting service will almost certainly provide it, for example via cPanel. Select your database and then the #__extensions table. Find the T3 plugin and then edit that record - just double click and change the enabled value to 0.

Do not delete anything via ftp. That could make matters worse because you still have database entries.

[Beata]

I am in my SQL
Sorry, I should maybe re-installation of Joomla

[ceford]

Just scroll down that list until you come to the sy4vm_extensions table. Select it to see the records in the table. Then find the t3 plugin and change enabled to 0

That might make your Admn interface work again!

[Beata]

Sorry,
I didn't find any t3 plugin in the extension.
