I am getting a serious error if I try to open the modules page in the admin:

Fatal error: Call to undefined function mb_eregi() in /home/gatewaytosedona/public_html/libraries/rokcommon/phpQuery.php on line 1422

I am really worried because I didn't make any code changes. Please help!

Thank you.

mb_eregi (and similar) is sort of a "core" function that most people compile into PHP so you have to contact your webhost so that they can fix this.

Like I mentioned above, this is more of a server environmental limitation rather than some code fixing. Please ask your webhost administrator to first confirm which php version is running on your site and to enable mbregex and mberegi functions of mbstring. I don't know which host you are on, but some hosts run multiple PHP versions so you may query the PHP settings and get the wrong settings since your site is running on a different version than the default PHP version.

I was working on things and it was fine, but just today changed. So I can't imagine what happened. I will call my web host, but it does make me think something happened when I was working on articles. What version php do you recommend? Also, what would happen if I were to remove that line of code where the issue is? Not a good idea I bet.

I called my host and they are upgrading php now... I'll let you know how it goes...

Min. Requirements
-PHP 5.3+
-PHP Multibyte String support
-PHP JSON support
-PHP DOM XML support

My host upgraded php and now everything is fine. And your super fast reply to my problem was VERY much appreciated. Thank you!!!
