cannot instal sp pagebuilder

Hi,

It's problem with your Joomla /tmp folder - you have to update path inside configuration.php file.
Right now you cannot install anything, even a small module !

I can guess you migrated site from localhost and forgot to update paths -
that's why Joomla still asks for folder from your computer.

Check also: administrator/index.php?option=com_admin&view=sysinfo
(all folders are RED = Unwritable)

Please:

1. Update path inside configuration.php file.
2. Correct folders permissions.
3. Update Joomla to 4.1.5.
4. Then you should be able to install any extension without any problem.

In big short that's all.
