Try another php cache like xcache or apc. Example, for xcache install run 'yum install php53u-xcache'.

[EndErr]

Don't know how but now i don't have the php installed. How to reinstall it? Did cleanup and fix-all already.

Any problem when using php 5.3 for your website?. Select php-branch in 'webserver config' to change php version.

[EndErr]

Can not select php-branch in 'webserver config'! On selecting and click on update noting changes.

[MRatWork]

Try change php-branch with 'yum replace php52 --replace-with=php53u'. Maybe something wrong in replace process and you will see in what's wrong in 'yum replace'.

[EndErr]

After doing that I've got php55 running thus php53 was prompting for install.
Try to replace it with php53 - no chances.
Removed php with php-common (because it was php55-common) and back installed php-5.3.28,
but now I can't install php53u-xcache.i686 cause php-common dependancy error,
"Package php53u-common is obsoleted by php55-common, but obsoleting package"

So. My server (with clients) is down for 32 hours No websites working.
Please advice what to do to have a working php and zend-guard (or xcache)!
Thanks in advice.

[MRatWork]

You have a problem with php in your server. Inform here 'yum list installed php*'.

It's better running 'sh /script/upcp -y' to 're-install'.

[EndErr]

Didn't work.
I've installed a fresh box and restored last valid backup.
But still can't use Zend Optiomizer.
After installing xcache nothing changed, the same "Zend Optimizer not installed".

Zend Optimizer is php cache like xcache or apc. Don't confuse with 'Zend Engine'. You don't need 'Zend optimizer' if enable xcache, apc or other php cache because make conflict.

That it!.

[chrisf]

Actually, Zend Optimizer is not a normal cache, but a way for php5.2 and earlier to display zend encoded files.  Your website is encrypted by zend, hence your error message. For php5.3+ they renamed it to zend guard loader.  Zend optimizer is no longer maintained, supported.  Zend guard is what you need.

First, download correct package from here:
(It is no longer called zend optimizer, now it is zend guard loader)
http://www.zend.com/en/products/guard/downloads

Then copy the files to your server, place the zend guard ini into the etc/php.ini directory.  Restart webserver and php by:
sh /script/restart-web

Now, your website will load

You should know this stuff Mustafa.
