Hi,
I followed all documents and instructions, step by step, to upgrade (actually in a test subfolder, of course) my website from Joomla 3.10.11 to Joomla 4.2.6. (template 1.5, uninstalling all not compatibile extensions, etc.)
In fact it worked fine at the first attempt, so I'm very happy now!
But a little (I hope) thing is unsolved: when I try to purge cache, I cannot remove this, as you see on attached images.
Please, Ivo, can you help me? It's a big issue or I can ignore it?
Thank you in advance.
