Tried to upload a custom app that is just over 15Mb and I got an error message telling me it was over 14 Mb. My PHP is set to max upload of 768 Mb. Any thoughts on where I should be looking?

 

Can you check what post_max_size is configured to? If it's below 768M, you can increase this to match it and it should resolve the issue.

Thanks Makoto! That was indeed one of the problems. The other - in addition to my stupidity - is that my WHM was configured with a default, but the specific domain was way lower. My WHM was 768, my cPanel was at 14. All good now, set all the PHP sizes to what they should be and I'm good to go. Thx again.
