Plesk CP not working - error 404

[davecates]

Hi,
I updated PHP to 5.2.5 last week and have got that working well but in the process seem to have broken Plesk!
To install PHP I downloaded the install program and ran that. It didn't work so I then downloaded the zip file and installed it as directed in these forums (wish I'd read that first!).
Anyway, now when I try to access our plesk login I get the following error:
"Invalid access to memory location."
I have Googled and found this is a MySQL issue. But, how does upgrading PHP break Plesk via a MySQL fault???
I have also tried 'repairing' Plesk via it's own repair program but no luck there either.
Anyone else seen this? Anyone able to help?? Do I simply update MySQL? Am nervous about doing so since my experience of upgrading PHP!!
Any help/advice much appreciated.

To verify the steps of correct PHP upgrade procedure you can refer to:

Note that some specific applications (as horde Webmail for example) do not work with PHP5 and should be configured to use PHP4.

As for Plesk CP issue - simply try to re-create Plesk Control Panel site in IIS by switching web engine to Apache and back to IIS:

%plesk_bin%\reconfigurator.exe --switch-plesk-web-server --new-provider=apache
%plesk_bin%\reconfigurator.exe --switch-plesk-web-server --new-provider=iis

Thanks for your reply.
Plesk CP is now working under Apache - much faster than it ever was with IIS!
Still having trouble though as now my PHP exec functions don't work
Any clues?

I've just found that, via using FileMon, when I upgraded the version of PHP on my server it not only screwed with my Plesk CP but also the permissions!!!
That was why I couldn't use the exec command from within PHP - even with CMD.exe set with permissions it was the IWPD_1 account that required permissions.
Hope this helps point someone else in right direction
