I tried switching the PHP version on AMPPS 1.8 (OS is Win XP Home SP3 fully patched) from 5.4 to 5.3 from the Control Center but I get errors for all the enabled PHP extensions (see attached screenshot).
Switching from PHP 5.4 to 5.2 causes Apache (httpd.exe) to crash and won't start again unless I switch back to 5.4. Any idea how to fix this?
