Hi. Blank page generally means a php fatal error. Most likely in this case
is php max_execution_time exceeded, but check the php error log to see what
it is.
Also you may want to check wgShellMaxMemory (i might be mangling the name)
The hash_equals is probably a bug, but probably an unrelated bug.

Hi,
I'm still getting strange error "Error creating thumbnail: Invalid
thumbnail parameters" for some images at bomosil.eu. You can see an
example
at
http://www.bomosil.eu/index.php?title=Soubor:Jihlava_-_zemska_hranice_Cech_…
.
As you can see I use version 1.23.15. The image itself can be find at
http://www.bomosil.eu/images/4/4f/Jihlava_-_zemska_hranice_Cech_a_Moravy_v_…
.
I tried to change $wgMaxImageArea to 10e7 (and higher). The error did not
show anymore. But there was a blank screen instead of it. No warning, no
error message, nothing.
Also when I visit Special:Upload I get a warning "Warning: hash_equals():
Expected user_string to be a string, NULL given in
/data/web/virtuals/27056/virtual/www/includes/GlobalFunctions.php on line
135". I don't know if this is interesting.
I also tried to upload the file at another wiki with success as you can
see
at
http://urbanecmwiki.8u.cz/w/index.php?title=Soubor:Jihlava_-_zemska_hranice…
.
The only one change which I made was that I changed
wgMaxImageArea to
bigger value. But this does not work in this case.
Could anybody help me with this?
The best,
Martin Urbanec
