Thanks for everyone's help, 
here is the error msg I get from two different wikis we have when trying to
browse the file gallery:

wiki 1:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to
allocate 11424 bytes) in
/home/myglcap2/public_html/usa/wv/ccmswiki/includes/media/Bitmap.php on line

wiki 2:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to
allocate 11264 bytes) in
/home/myglcap2/public_html/usa/wv/hsta-manwiki/includes/media/Bitmap.php on
line 168

This might be caused by the imagesize as Grietinus wrote yesterday (Issue
10) I am not sure.

The wikis is setup on a shared server.

The solution I found for it is:
1. Chaning Memory limit from 20M to 40-50M on the following line of
# ini_set( 'memory_limit', '20M' );
2. Going to the file gallery (that works now) and clicking on the thumbnails
3. then lowering the memory back to 20M

Any clues of how to prevent this?

I also encountered this problem.
However it does not seem to be related with the bytesize but more with the
imagesize. Whenever an image exceeds the size of approximately 1600 x 1600
pixels, the "Fatal Out of Memory" errors occur.
It is, as Norbert says, only when Thumbnails are involved...

Kind Regards,

Hi all,

I am trying to alter the monobook skin and I am running into a weird 
problem (version 1.5.5).

Some links are still "clickable" while others behave as simple text, but 
are displayed in blue.
When I have a look at the source of the webpage, the links are displayed 
exactly the same.
The page in question is at 
http://gemologyproject.com/wiki/index.php?title=Habit&useskin=test .

The first "form" link is not clickable (first sentence in the Basic 
section), while the 2nd "form" link (in the Related Topics section) 
works as expected/hoped.

Another strange thing is that I can not highlight the text in the 
"Basic" section. I'm sure the two problems are related.

Does anyone have an idea what causes this?
