DEBUG - How To Deal With Blank Pages Or Only Header Shown

If you can see only the header of your forum or just a blank page, take a look if you can change the memory limit value and solve the problem.

add at the top of common.php

Code: [Download] [Hide] [Select]

ini_set("memory_limit","12M");

Some times, a Fatal error: Allowed memory size appears also. The fix for that problem it's the same written here

Re: How to deal with blank Pages or only header shown

Maybe this is not the right solution for all, but it is worth trying.

I would like just to remember that you can increase MEMORY LIMIT in several ways and not only via PHP code (which should be allowed by your hosting though).

You can increase memory allocation by editing HTACCESS or PHP.INI as well. Of course your server should allow HTACCESS or you should have directly access to PHP.INI.

This is the code to be added in HTACCESS if you want to try:

Code: [Download] [Hide] [Select]

<FilesMatch ".(php|html?)$">

php_value memory_limit 16M

</FilesMatch>

Sometimes it is a double inclusion, or a double function declaration... @nene94, BUT if you had to delete some lines the problem was, I think, memory limit... @ULTRAMAX, I don't see blank page...

Faults / corruptions in def_themes.php and def_tree gives just a white page

Re: How To Deal With Blank Pages Or Only Header Shown

Well, I'm not getting the white page of death anymore (see my post above), but when I try to post a new message I get:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 3545735 bytes) in /home/xxxxxx/public_html/forum/includes/functions_categories_hierarchy.php on line 416

I've already tried the solutions above, but no joy. Can anyone help please?

Re: How to deal with blank Pages or only header shown

I have checked your site, and I'm not 100% sure... but 90%... that your problem is related to the number of subforums...

It is not good having hundreds of subforums... users won't ever be familiar with all those subsections. Anyway it is your site, and you are free to organize it as you like.

The problem in having so many subforums is that for each forum many informations are stored and are retrieved while posting and while browsing topics... for each forum permissions are tested and stored in memory... if you have hundreds, then you have hundred of checks, and the system could run out of memory, and sometimes showing up white pages.

My advice is:

Make a full backup
Check that your backup is correct
Make another DB backup using a different way just to make sure you don't have to recreate manually all those categories
Trim subforums until you reach maximum 40 / 50 forums
Try again to create new topics / posts

If you really need all those subforums... you may consider moving to another system because Icy Phoenix is not optimized to have so many subcategories. phpBB 3 should be able to manage all of them correctly.

tc1967uk Joined: March 2007 Posts: 129 Location:	Re: How To Deal With Blank Pages Or Only Header Shown Would changing most of them from forums to links save a lot of memory? Is it just categories and forums that take up a lot of memory, or would links too?
