Blank Admin pages after checking forum [Solved]

[Aureli]

Hi,

After I upgraded to 1.6.6, it worked fine and after a while I could not see the Admin area.  It only shows a blank page but the site is visible.


I have been checking the forum for solutions and I have tried a few things:

Changing $config['debug'] to true did not show anything, still all blank.

I increased the php memory setting in config.php to 32MB and got the message:

Fatal error: Allowed memory size of 262144 bytes exhausted (tried to allocate 4864 bytes) in /home2/wwwsand/public_html/lib/smarty/Smarty.class.php on line 853

Is this a problem of the server's memory limit?  I checked my host and it seems that the memory_limit is set to 16MB.  Should I contact my host and ask to increase it to 32MB?  It says  in their info:"the maximum amount of memory a script may consume 32MB"

I have read in a post that admin pages are rendered from the Plugin folder but I have not modified anything there.
All I have done is adding modules and modified CompanyDirectory and added FEU for testing.  That's all.  could this have anything to do?

The site still works well in my local machine.

You have 25MB (26214400 and not 262144 bytes)
More modules you install more memory is necessary, try to uninstall FEU and ask to your provider to increase to 32MB, you can test from System Information or an php file with phpinfo();

Hi,

I have run the phpinfo(); and it does say that memory_limit is 16M.  I'll contact my provider and ask them to increase it to 32M.

In the meantime I can't access the admin area to uninstall modules onstalled via the Module Menu,  could I "uninstall" modules by deleting them from the server without breaking other pages ?

Rename folder name but BETTER if you have a sql tools is update [cms_]modules table with 0 in active field for that module (remember of update to 1 after)

Thanks Alby,

Still not working...

I have changed the Active field to 0 in the cms_modules table and left to 1 the ones they are pre-installed (CMSmailer, FileManager, MenuManager, ModuleManager, News, Printing, Search, Theme Manager, TinyMCE).

If I use the wrong details to log in it does say that details are incorrect, but if they are correct it just shows a blank page.
At least the site is still visible.

I will ask my host to increase the memory_limit to 32 and will update with results.

A.

[Aureli]

Well, now I am really stuck!

My host has expanded the memory_limit to 32M
safe_mode if off
I have set to 0 the values in cms_modules table for many modules so they don't use that much memory

I still get the blank page when I log in in the admin area.

I forgot to mention earlier on: Firefox 3.5.3 tries to download the index.php file after login in.  IE is just showing a blank page...

Any other ideas?

Any other ideas?

Always you must check server logs and active debug in config.php

[Aureli]

There are only 2 300 error messages, the second one is pretty similar to what I got earlier on:

[Thu Oct 22 19:17:15 2009] [error] [client 194.125.102.99] File does not exist: /home2/wwwsand/public_html/favicon.ico
[Thu Oct 22 18:07:13 2009] [error] [client 194.125.102.99] PHP Fatal error:  Allowed memory size of 262144 bytes exhausted (tried to allocate 4864 bytes) in /home2/wwwsand/public_html/lib/smarty/Smarty.class.php on line 864

Line 864 is the following one and I have no idea what it does.

Code: Select all

function register_prefilter($function)

I have activated the debug (i have set it to false again) and it showed  messages in the index page (see below).  The Admin page was still blank.

To me it looks like is not showing anything important but it wouldn't in the front page, is teh admin area that is not shown and there is no debug messages there.

Don't know, do you think a re-install with the basics will help?

I have activated the debug (i have set it to false again) and it showed  messages in the index page (see below).  The Admin page was still blank.

Sometime you have a blank page because html code is broken
Active debug and look in html "source" of admin page

However bed things with your php memory error, what you have in $config['php_memory_limit'] setting in config.php?

Alby

[Aureli]

Hi,

I left the $config['php_memory_limit'] empty.  If I put 32MB I get this error:

Fatal error: Allowed memory size of 262144 bytes exhausted (tried to allocate 4864 bytes) in /home2/wwwsand/public_html/lib/smarty/Smarty.class.php on line 853

If I activate debug it the admin page stays blank (after clearing cache and reload) and source shows a blank page too...

Well,  The problem is fixed but don't ask me how.

The problem started a few days after installing the modules for FEU and CompanyDirectory.  I had them, installed, working and tested and after more than a week of not doing anything I started to get the problem of blank pages once I logged in.

I set the modules to inactive from the database and contacted my provider to extend the memory to 32Mb.

Still had the same problem for nearly 2 weeks more and yesterday, when I was ready to spend some time uninstalling and isntalling the whole thing, started working again.

Since I have tried a few things I'm not sure what has made it work again.

I hope it continues working now!

Thanks for your suggestions, Alby

Just bumping this issue in case somebody has discovered a remedy for this.

Have gone through all of the above.

I have two sites that this has happened to.  No obvious reason.

Both sites had not been administered for a few weeks weeks  (that is, no admin login) but when we recently attempted to login we received a blank page on successful login.

Both sites have CTLmodulemaker installed also  FEU

CMSMS version 1.6.5

I'm now living in fear that this will happen to all my CMSMS sites.

Hi Lemonaid,

Have you asked your provider to expand the memory limit in the server?

I am not sure what worked for me but I'm sure it was that.  The more modules you use the more resources cmsms will need.

This problem was solved for me and has not happened again.

I hope you get sorted soon.
