Thanks for your reply. The copy & paste is below.
I could actually do with help with my 2x WordPress sites; 1 of them keeps sticking on the scan, and the other tells me that there are 3x modified files.
I have no idea what I'm looking for and would even pay to have someone have a look at it.
Anyway, here's the data;
Wordfence Memory benchmarking utility version 4.0.3.
This utility tests if your WordPress host respects the maximum memory configured
in their php.ini file, or if they are using other methods to limit your access to memory.
--Starting test--
Current maximum memory configured in php.ini: 268435456
Current memory usage: 38.50M
Setting max memory to 90M.
Starting memory benchmark. Seeing an error after this line is not unusual. Read the error carefully
to determine how much memory your host allows. We have requested 90 megabytes.
Completing test after benchmarking up to 80.25 megabytes.
--Test complete.--
Congratulations, your web host allows you to use at least 80.25 megabytes of memory for each PHP process hosting your WordPress site.
