Hey, guys, I'm having a big problem that is causing loss of customers  , I already test in the demo and it is the same error.

Here is the history...

I update my PHP7 max file from 2M to 10M http://lakompra.com/phpinfo.php the thing is that when someone with a new phone takes a picture and try to upload it is taking a long time, we are talking about 3 MB- 4 MB per picture (new cell phones).

The main problem is if you fill out the form and click on submit or publish and the picture still uploading you will see an error message that said "stay in the page" if you click on that and wait for the uploading images process, and wants to click again on submit or publish the button doesn't work.

You can click many times in publishing and is not doing anything, my question is,

1. there is a setting in my PHP that I can change to speed up the upload process? (I have imagick php)
2. to have an easy resolution there is a way to disable publish button while the pictures are uploading? 

you can test this error under the m-b zara demo

BTW I also have the Invalid CSRF token 

@Carlos
Whole process with image uploads is managed by osclass core, so you may need to submit bug to osclass itself.
You need to understand that if there is limit 2MB, osclass needs more space to handle this file (crop, add white background, ...).
