XF 1.5 PHP 7.1 upgrade created issues

[hyperthreadz]

For special reasons, it was needed to upgrade a site to 7.1. This caused a myriad of issues, most of which have been resolved.

The site was working very well until the 7.1 upgrade.

One issue that has plagued us is when a user uploads a photo, large in size, it fails to display, or create a thumbnail. It suggests the image has uploaded and reports in the attachment manager. In the post or reply, it will display but only as a link such as View attachment photo.jpg. Any smaller photo/picture will display the appropriate thumbnail and/or full sized photo. However something such as a 8mb 9000x9000 pixel photo refuses to cooperate.

I've edited appropriate PHP.ini settings such as:
memory_limit 256M
post_max_size 256M
upload_max_filesize 256M

I've upgraded Xenforo to the latest 1.5 version available.

The only attachment addons I'm using are:
Insert Attachment 1.6.
Convert Image (disabled for testing)
Convert Image All (disabled for testing)

If I edit the config.php and enter $config['maxImageResizePixelCount'] = 100000000; it gives me an error message when uploading an image.

Tried setting Maximum Attachment Image Dimensions to 10000x10000 to ensure a 9000 x 9000 should work.





tl;dr: Upgraded to PHP 7.1. Small pixel / large images upload fine, large pixel / large file files fail uploading.

If anyone has any ideas/thoughts, I'm all ears. I'll check back in the morning.

Are you using GD as the image handler, or Image Magick?

We have both installed but are using GD 2.

After much testing, I think this part is key to my issue:
> If I edit the config.php and enter $config['maxImageResizePixelCount'] = 100000000; it gives me an error message when uploading an image.

Any images falling under the base 20000000 work whereas anything over upload and I get a link.

Thinking there might be something to the size, I went down a factor of 10 and re-edited the config (putting the code back in).

$config['maxImageResizePixelCount'] = 90000000;

However, upon doing so, I still get this:

The following error occurred
There was a problem uploading your file.
