upgrade php 5.2.13 to php 5.3 or later

[decaPeter]

Hello,

i'm trying to upgrade the PHP version from 5.2.13 to a new 5.3 or 5.4

But, while i replace the "/Plesk/additionnal/PleskPHP5" folder with a new version (with a copy of the original php.ini) i have a 500 error on all pages.

I've tried 5.3/5.4 thread/no thread and reboot server on all try.

Can i use directly a php version from php.net or do i have to use a specific version from plesk ?

Thank you for your help.

Hi decaPeter,

Yes, you can use php from php.net
We have KB for that: http://kb.parallels.com/en/6670

thank you but that's what i did with this KB page... but i have the 500 errors.

decaPeter,

I suggest you to take a look on Windows Event logs. Perhaps there will be some errors connected to php.
Also it is good idea to check ownership an permissions of new PHP folders. It must be same as in "/Plesk/additional"

 

[decaPeter]

i've already checked ownership permissions and its the same as the original PHP5 folder...
i have succesfully read the phpinfo file without 500 error but all other pages are in 500 error (phpmyadmin, joomla, own script)

strange?

If you are sure that your PHP script with phpinfo() works, then these '500' errors could be connected with PHP extensions.

Plesk supplies compatible PHP extension libraries for particular OS (bitness, tool that used as compiler/linker == VS9, as example).
If you are using not compatible PHP extension libraries, then PHP scripts will crash on run-time.

You can try to disable PHP extensions (say, php_mysql.dll) and then try to open joomla.

Then you should check IIS error log and Windows events for details.

yes, i have specific extensions like ffmpeg installed with the old PHP5.2. Maby i have you disable all old specific extensions to test the new version 5.3?

thank you again for your help.

now i can run php5.3.23 but the MySQL connection is down. i have a message "#2000 mysql connection forbidden" on phpmyadmin when i try to login.

Maby that's why i have a 500 error on all websites???

 

[decaPeter]

ok so... i have new information. I can now lunch and use phpmyadmin and all websites BUT with a mySQL user with no password.

It seems to be a problem of mysql users passwords. So i can use phpmyadmin with the user without password but when i try to change the password of other users, it doesn't work!
Do you know why all mysql password are broken? I read something about hash 16 char or 41char. (i have MySQL 5)

can you help me please?
