Hello!

After upgrading from 2.0 prerelease to 2.0 stable, i get this error message:

Fatal error: Call to undefined function mb_ereg_replace() in /mnt/web4/53/33/51645033/htdocs/administrator/components/com_k2/tables/k2category.php on line 49

I searched the forum, and the solution seems to be to enable the MBstring, however, when I look at my PHP settings in Joomla, Multibyte string support is enabled.
What could be the problem?

Thanks in advance!

mb_ereg_replace is from subset of multibyte string functions that deals with regular expressions. IMHO You can have some of mbstring functions enebled and available, but not those related to/dependent on regex use. Might require additional configuration for php if not already enabled by default.

Thanks for you reply, Valdis. I got it working by removing the mb from the mb_ereg_replace in the PHP files. I hope this will not cause any problems when upgrading. Probably I'll have to do that exercise again....

I just upgraded to 2.1 and get this error when saving an item:
Fatal error: Call to undefined function mb_regex_encoding() in /mnt/web4/53/33/51645033/htdocs/administrator/components/com_k2/tables/k2item.php on line 72

My hosting provider says I can write a php.ini file and try to enable the mb_strings. Any ideas on how to do this? Thanks so much again!

I had the very same problem and just uncommented "extension=php_mbstring.dll" in the php.ini file(I use PHP 5.2.11)
It works like a charm. Hope this helps.

Okay, I guess I have the same problem:

Fatal error: Call to undefined function mb_regex_encoding() in /home/toukoaal/public_html/components/com_k2/helpers/route.php on line 56

But I have to admit I have no clue what you guys are talking about. Could somebody be so kind and explain what causes this and how it can be fixed?

Thank you in advance.

Okay, this is getting ridiculously hard.

I have no clue wht php.ini file should look like in this case.

Is there any use to just uninstall the whole thing from server and install it all again instead of copying files and databases or do I waste just another tremendous amount of time if I start that operation?

Ok, good to know. I solved my problem by being in contact with my server tech support, they were more than happy to help. They just installed mbstring.dll.
