I am attempting to install the X plug-in. The host is running PHP 7.4 FastCGI.
Initially, I instlled pro via the pro.zip file. The installation appeared to complete successfully, but then I made what is possibly a misake; I clicked on the link to the installed plugins page instead of the “Activate” link.
The X plugin did not appear on the list of plugins (as activated or otherwise). If I try to install X Pro again, Wordpress just tells me that the install failed because the file contained no valid plugins.
I have no idea what to do at this point; I have been able to find any report of the same or similar problem.
