I'm unable to save css/flat_and_modern.css when editing my template (which is a copy of the default template).
The only thing that comes to mind is that it's a 7000+ line file.
When I submit the changes, after some time, I get an 'connection was reset' error in my browser (Firefox 48.0) and the template doesn't appear to save. To resolve the issue and implement my changes, I had to edit the file locally on the server, save it, then copy the template and implement the template copy (implementing the template doesn't appear to get the files from the new template folder by default).

Is this possibly a php setting relating to upload size? Is there anything else I should be looking at? All other files (considerably smaller) save fine. Any assistance would be appreciated!

*EDIT* Looking at the network tab while inspecting the page on POST, 128k is transmitted but nothing returned. That does sound suspiciously like a round number. I'll check php settings...
*EDIT2* Nope - 8M upload limit with 2M file size... can't be that surely. I notice that particular template file is around 156k... I'll try making it smaller just to see if there's a threshold I need to be aware of.
*EDIT3* It stops responding when that file is around 4500 lines or bigger, so definitely related to the size of the file when submitting. It's hardly big though, so there must be a setting somewhere.

I'm running on IIS and MS SQL Server. with php 5.5 on Win server 2012 R2.

Where is this template located? In which folder?

There might also be a limit for the PHP porcessing time, which could be a problem. Or your memory size limit.

Memory size is 128M
The template is located in the default folder (I just copied the default template). All the other files in the template submit without issue, just that one file won't submit for that template.
I'm not sure about the processing time but it would have to be ridiculously short to not be able to post a 7000 line text document I think. 4000 lines will go through - usually within a second or less...

I'll see what else I can find, if you have suggestions on what setting the processing time for php is that would be great,
Thanks!

New templates should be copied to the /upload/templates/ directory.

Try setting "debug" to 1 in /application/config/config.php. This will cause the template files to be loaded directly from the template directory instead of from /tmp/assets/.

Any idea why that might help?
As mentioned, it's able to submit and update the file if it's 4000 lines or less, but 4500 or more and it doesn't succeed.

I'm not sure when the template gets compiled to /tmp but that may be the bottle-neck. Did you try it?

Not yet, but I will shortly,
Cheers
