I have a problem with a Joomla! site that I did not build. It is due to memory being exhausted. When I try to install I get this message:
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 24576 bytes) in /home/xxxxxx/public_html/libraries/src/Table/Nested.php on line 1340
I'm sure it is not a memory issue as I have raised the memory limit (in the hope that I would be able to update Admin Tools and Akeeba Backup at least whilst I troubleshoot).
Previous to this, I had a problem with duplicate IDs in the extensions table. I manually updated these by using phpMyAdmin to download a CSV and update all the duplicate 0 IDs with incremented numbers.
I have disabled any extensions that I don't recognise except Joomla! Core.
I have reuploaded via FTP all the latest Joomla! files.
When I look in extensions > Manage, I find multiple copies of things like F0F3 and even templates like Beez and Hathor. Uninstalling them removes them all, so I'm keen to avoid that.
Firstly, how can I remove the duplicates? My guess would be that duplicate extensions would take a lot more memory if all being activated at the same time.
I see multiple copies of the Akeeba in the extensions table, but I don't see it in the admin menu. The same with Admin Tools.
The Admin tools plugin does not seem to exist.
I'm concerned this is a hacked site if I'm honest.
