I transfered several sites from one web server to other and it looks this only one have problems. This was Xoops 2.4.4. and I get only blank page on index page.
I can login with user.php, and go to admin.php then, even use some options in admin part. I tried to upgrade to 2.5.3 but after that everything is even worse than before.
Now I can't use module administration nor upgrade modules.

site is: http://os-tadija-petrinja.hr

Here are messages that I get:



I tried to upload multimenu again but nothing changed.

This is what I get when I try to enter module admin part:



So this is my configuration:
Xoops 2.4.4 (when I transfered)
Xoops 2.5.3 (after upgrade process)
PHP 5.3.8
MySQL 5.1.56
Apache 2.2.21

Maybe someone can see what cause this problem.

Thanks in advance

mb_substr() missing means that you don't have "php_mbstring" php extension enable in your server. Your xnews module requires it to run. If you can't enable it, then edit file "/xnews/blocks/news_top.php on line 457" and replace mb_substr by substr (just remove the mb_ prefix)

unrecognized tag 'xoAdminIcons' means that you are missing some smarty/xoops_plugins that are required by Frameworks/moduleclasses

Try copy all xoops_plugins from a full Xoops package, maybe the upgrade package is missing them.

I assume your PHP is now 5.3.8 (not 3.5.8 as stated above). This is why you're getting the 'eregi' DEPRECATED notices. While these are unnerving, they're not fatal and shouldn't cause any operational problems for now. Trabis is right, focus on fixing the 'mb_substr' Fatal error and re-uploading the XOOPS /Frameworks/moduleclasses directory (and subdirectories) to clear up the Smarty issues.

Thank you Trabis!!! You save me lot of work here!
I purchased new VPS for my little firm and php_mbstring wasn't enabled by default.
I still have this xoAdminIcons problem, but this is only in the back where nobody see this. I'll fix it later.
And BTW I swith back to PHP 5.2.17 on my server, OSCOmmerce also have problem with several functions.

and yes zyspec, it was 5.3.8. I fixed this in first post

Thanks you all ones again

Well, I tried to copy all xoops_plugins (what I done before also when I made upgrade of site) and I still get this error when I try to click on modules administration.



When I tried to administer multimenu module in admin panel I got this:

Well, this wasn't last to much
Again, I can't open site, now, every page (index, admin or user.php) doesn't work.

I again look att smarty/xoops_plugin and find out this:

Old files were named like this: compiler.xoAppUrl.php
and new one with xoops 2.5.3 like this: compiler.xoappurl.php

So this make problems.
I changed lowercase to upper and now site works again.
Also I made that for all files that were writen in error and now all works.
I don't know why this happen, I recently made several succesfull upgrades from 2.4.4, even older xoops and this was first time this happen

I found that lowercase problem was related to my Total Commander that has, by mistake, used lowercase upload.
