Issue solved, got help from a programmer. An array got bigger than 128 MB, he changed the code to fix the issue.

I'll paste what he wrote when he found the issue, use Google translate to translate from Swedish to English if needed:
"I /www/kernel/groupperm.php (xoops egen kod) har vi en funktion som käkar nästan allt minne. Den skapar ett objekt per rad i group_permission.

Här ser ni hur minnet går åt nästan helt:

Vad används denna gigantiska array till sen?
Jo, den förrut omtalade permission-loopen konverterar den till en ny, mindre array, varpå den förra frigörs."

Hi,

This was originally posted in another thread (https://xoops.org/modules/newbb/viewtopic.php?start=10&topic_id=76447&order=ASC&status=&mode=0 ) regarding forum issues with newbb and then smartsection issues but think this issue could require an own thread:

The main page does not load, just blank. Newsitems in smartsection load as they should for examplehttp://vaken.se/modules/smartsection/item.php?itemid=2389

But going directly tohttp://vaken.se only works sometimes, seems a bit random, sometimes it works directly and sometimes 10+ refresh does not load the page. It shows a blank page with no content (0 kb).

Web hotel support found this in error_log:

[18-Nov-2013 02:36:10] PHP Warning: unlink(/home/vakense/public_html/xoops_data/caches/xoops_cache/xoops_system_modules_active_http%3A%2F%2Fvaken_se.php) [function.unlink]: No such file or directory in /home/vakense/public_html/class/file/file.php on line 328

file.php and line 328 is the following:
return unlink($this->pwd());

Could the error found in error_log be an explanation or our issues?

This is what our XOOPS "expert" had time to find when looking in the other issue with smartsection, uncertain when he will be able to look at the issue again:

"Look like it's related to templates. Smarty is the name of the program that manages templates for xoops. This program manages templates_c och
the cache folder.
_
It looks like this have stopped to work. template_c used to be full of files and is now empty."

After this web hotel support changed rights to 755 for folders and 644 for files. The problems with the main page loading blank actually started after this but according to the web hotel this was the correct settings for suPHP. Be saying it started after this the problem became very common two days after changing rights for folder and files, I can't quite remember is it was an issue the same day the file rights where changed.

I don't know if it's allowed on this forum but if it is we are considering to hire someone to look in the issue and troubleshoot, with an extra reward if the issue is solved, main problem is that the start page just loads blank most of the time.

From what I have heard reported and experienced myself the issues started with seldom occurrences of the main page loading blank and increased.

Hi,

The forum module we had problems with earlier was newbb.

Unfortunately we got bigger problems than the fixed forum problem and still existing smartsection issues.
Think that the problem might be related so I'm continuing in the same thread. We are a bit lost as the person who built the site and has the deep knowledge of XOOPS have very limited time to look in to the issue so bear that in mind.

Now the main page does not load, just blank. Newsitems in smartsection load as they should for examplehttp://vaken.se/modules/smartsection/item.php?itemid=2389

But going directly tohttp://vaken.se only works sometimes, seems a bit random, sometimes it works directly and sometimes 10+ refresh does not load the page. It shows a blank page with no content (0 kb).

(Several of us managing the site share this account vakenpunktse here on xoops, if you wonder why we write diffrently)

Status: Now this Fu.... S... has moved over to SMARTSECTION. So ADMINS cant edit newsitems. Just blank screen when pressing edit. Xoops has worked like a charm since 2004, and now this happens. Gaaaaaaaaaaaaaawh!

The extra bad thing is that the problem isnt consistent, and some smartsection items are edit:able, and some arnt.

All tips and hints are very helpful. Our Serviceprovider has not done any PHP-upgrade lately. They run on 5.2 and will upgrade to 5.3 in near future.

Lovley start on a saturday. Thanks for all help guys.

Issue solved, our XOOPS-expert got some time and deactivated a module that was causing the issue. Not sure why that particular module was causing the issue but working fine now. Will consider upgrade anyway.

Hi,

From what I can see in XOOPS System administration we are running XOOPS 2.4.3.

Have not gotten answer yet from our host on which version of php they are running.

Hi!

Im a novice at this and our main maintenance guy is not available for some time, so please overlook if I describe our problem in the wrong way or if I make mistakes you may regard as simple.

The short story: We really need help because when logged in as webmaster/admin an you open any thread in the forum, the sites just loads i totally blank. See print screen.

If a reg user logs in, everthing works fine. This problem has never happend since 2004 when we started using xoops. Totally new problem that just came some weeks ago. No usual reguser, have ever complaind the last weeks, just admins complaining.

This is a printscreen that shows how it looks for admin.


Our forum-module i version 3,08.

Have you guys ever heard of this problem and have some tips where to begin.
Space on server is ok 1,5 GB free.

Please dont just answer "upgrade" to Xoops, or module bla bla. Because that could be a big process and lots of individual data could be lost which I cant manage. I really need to get in contact with someone who have heard of this problem or can give me some hints where to begin. When a reg user uses the forum there are no problems at alls. But for admin-users with webmaster-lever, you "had" to reload the thread in the forum several times before the site loadad. But now it just loads a white screen even thou one reloads many times. Is kind of annoying becaus it isnt a static problem and "sometimes" work when you reload several times.

All the best from sweden. And many thanks for help and hints. I may have forgotten to describe something here. So please just answer in the thread i you need more info. We have about 40 000 unique visitors per month and this is becomming a nucians for the webmasters / admins.
