[SOLVED] CB 2.0.9 Joomla 3.4.1 CB Gallery 1.0.3 Some Photos Not Uploading At All

I am a new developer to Community Builder and I have officially hit my first speed bump. I launched a website and users are signing up, but I need them to upload photos into their profile and for some reason, some work, and some don't. I'm running mod_security on my server, so I am trying to investigate that also, but since this site is live now, I am trying to be humble and ask those who are much smarter than me, which may be this entire forum, if you can lend any assistance.

Thank you in advance for all of your help and support.

Anything common about the photos that don't upload? Any errors? What happens when trying to upload? Tested with debug mode and maximum error reporting enabled? My first guess is you're hitting memory limits while trying to upload a very large photo (width by height wise, but filesize can contribute to this issue).

Wow! Thank you for the reply...

I did try to investigate to see if mod_security was the culprit. This is what I am seeing thus far in the error log.

See error_log_text.txt

I was told this by someone else... The "PCRE limits exceeded" error can be caused by a few things, generally if you see this you will also see a different error before hand that can be corrected to prevent the limit from being reached, however there are a few changes required if this does not come whit another error.

As for your questions...

1) There were no specific correlation that I could find between the files. The one that wasn't working was taken with an iPhone 6 and was a 1.8 MB JPG. Not the largest or the only iPhone 6 photo.

2) No visible errors at all. The screen just went white and everything stopped.

3) This issue only occurs during an upload attempt when the specific file does not work.

4) I did not text with Debug Mode or Maximum Errors, however I will attempt to do that now.

I just turned on Debug Mode and put Error Reporting to Maximum.

This is what I saw...

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 31961089 bytes) in /home/pestalen/public_html/libraries/CBLib/Imagine/Gd/Image.php on line 617

Someone suggested that I add the following to /usr/local/lib/php.ini

pcre.backtrack_limit = 10000000
pcre.recursion_limit = 10000000

And also add the following to /usr/local/apache/conf/modsec2/custom.conf

SecPcreMatchLimit 150000
SecPcreMatchLimitRecursion 150000

I made both changes, but I am still seeing the error below:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 31961089 bytes) in /home/pestalen/public_html/libraries/CBLib/Imagine/Gd/Image.php on line 617

Yup, you're hitting memory limits when the image is trying to process. You've a few options to avoid this. The first is to increase your memory limit, which is currently set at 128mb (recommend 256mb for large photos). Another is to limit the maximum upload size of photos, which doesn't help that much as most of the memory usage is from the photo exploding to raw data. You can also try using ImageMagick which is more optimized than PHP GD2.

Increasing memory limit is likely going to be your best option. The reason for this is you image maybe just 1.8 MB (btw, that's huge for an image; that's like raw uncompressed), but if its say 4000x4000 that's a massive amount of pixel data. Images are processed by their raw pixel data, which takes a ton of memory if you're uploading a huge image.
