Because I have some hosting/security issues when 30 students on one IP address visit my site at once, I was looking on the web for possible solutions. Could the fact that I use php 7.3 with my hosting be an issue? Should I choose 7.2? And should I change any of these settings: https://imgur.com/a/9OPBB49
Alex, just 4 weeks ago, said there are issues with 7.3 --> https://wplms.io/support/forums/topic/is-wplms-compatible-with-php-7-2-0/
Also. Is it useful to set database, redis and object cashing in W3 Total Cache or does lower speed and create the blocking/temp unavailable issues I have?
Hello,
Yes, you can use 7.2. I have discussed your situation with Alex. he said yes it could cause issues with ajax request. its better to use php version 7.2 for now.
