Zend Guard and Zend Optimizer are programs used to obfuscate and then run, or decode, the obfuscated php source code.
Are you asking because you believe you have found php code obfuscation in the theme?
I have a plugin I want use in WordPress. I have use the theme and the plugin on another site but when I updated WordPress I get an error message about the theme and Zend. O contacted my host provider he told me to verify which Zend to use because it can cause site to crash
when I updated WordPress I get an error message
What version of php is your web site using?
You mentioned a plugin that’s involved, a WordPress update that caused the error, and an error message that’s related to the theme. So it might be the theme, it could be a plugin, or it could just be a bad host.
If you copy and paste the exact error message here so someone else can see what it is, and also include the name of the plugin that you have concerns with, someone might recognize the problem and be able to help.

I contacted my host & the rep stated it’s the theme but I have used it successfully previously
That message in its entirety is amazingly specific, very instructional, and extremely self explanatory. The plugin appears to quite clearly be the cause of the error. It appears to have nothing to do with the theme or with WordPress, and your host just plain doesn’t want to be bothered with it.
Call your hosts back and ask them how to enable the extension (ZendGuardLoader) in your php5.ini file. Better yet, ask them to do it for you.
Wow, thank-you! The host made it seem that it was the theme. I couldn’t understand why it worked once then after an upgrade it didn’t. When he told me that the site might crash if I installed the wrong one I wanted to cross Ts & dot Is.
The host provider fought me tooth and nail but I was adement about holding them accoutable for this issue. At first they only emailed me the instructions stating they could not change the file for me. Then the rep attempted to blame the the plug-in creator. Then finally I made my point clear that the buck is stopping with them. So the rep finally gave in and walked me through the process.
** You have to rename the current php.ini or php5.ini file to something else then create or modify the php5.ini; php.ini will not work.
