Question [SOLVED] File Upload Failing broken css

Hi
I'm running out of things to try with this problem so I thought I would ask here before I entierly destroy my site, I'm afraid I've not been able to find an answer elsewhere here - sorry if I missed it.
I upgraded today to 1.6 - all seems fine apart from...
I get the no css, or broken css view of my site when uploading some images. Checking with Firebug and the server log reveals a http 500 error.

1. I have pretty much removed every plugin and module with no effect.
2. I have run the site (prior to upgrade and since) on a local windows apache server and I cannot recreate the fault even with all plugins and modules enabled.
3. I have uploaded the same image here (in the playground forum) without fault.
4. If I rename the file or upload to a different thread, or using a different browser the fault is the same.
5. I have disable MIME checking - no change.

If I resize the file on my local computer then upload it works fine. Other images both larger in size and dimensions work without fault. I can't find anything to predict which files will be affected, however those that are, are affected consistently.

It seems to me that there must be something to do with the file and the image processing that is causing the problem - my host? It does seem to relate to specific images, but really I am out of ideas so any suggestions would be most appreciated.

Here is the (or at least one of) file that fails to upload to my site...



Thanks in advance.
Rob

Coincidentally (or not) I got a 500 error when trying to output the config (as below) but I tracked this down to a missing file in the uddeim install..

Hi,

Thanks for reaching out. Your issue is most likely a simple issue. The missing CSS is not an indication of anything being wrong with your template, nor will this do anything beyond that page view.

As you already found out is the 500 error. This means some php code aborts and fails. This could be a missing library or some other conflict.

The way to find out quickly is to look into the apache server error log. You should find that on your web hosts control panel under something like log manager. That error log will include a cleartext error message that will tell us what is wrong.

Hope this helps!

Hello fxstein, thanks for the quick response.
The very odd thing is that in the server access log I see an entry like...
"POST /forum/post HTTP/1.1" 500 2670 "
but in the error log there is no corresponding entry - no error reported.
However Firebug shows a 500...



I will download the logs and have a proper look tomorrow - I could be missing something as the server is busy at the moment and I am not too quick to spot things in the logs!

Thank you
Rob

The server access log will not include any errors

Its the server error log that you want to look at

Hi fxstein
I know you are correct of course - but the error log shows no sign of the problem despite the 500 being shown in firebug - its a new one on me.

I went to my host to see if there was some other log I didn't have access to (this site is on a shared server), but they confirmed the 500 was not showing in any logs.

They suggested that I increase the memory limit through php, which was one of the first things I had tried - so no joy there.

They then suggested I increase the memory limit available to the server in the .htaccess file using the following statement...

RLimitMem 128000000

Initial tests suggest that this has cured the problem. Its not a setting I have come across before as I have always managed to resolve memory issues using php.ini.

Hopefully this is the solution and the fault stays fixed and this thread will help others in the future.

I'd like to thank you all for your work on this release - the install and migration was flawless thanks to information provided through this site. I love the new features and I'm sure my users will too.

Thank you
