Using Chromebook submit form and get Internal Server error

Hello,
One of my student tried to submit form using Google Chromebook and he got Internal server error. He tried 3 times and got internal server error every time. I have more than 40 students who can submit without this issue. Please advise where should I start to investigate.
Thank you,
Nilubon

Hi Nilubon,

1. Check the server logs to see if there are any clues there.

2. Use the browser web-developer tools on the student's computer to see if there are any clues there in what is being submitted and the response you get.

Hi Bob,
Finally I just got a respond from a student who has an issue with Internal Server error. It turned out that his file name has an apostrophe and it gave that error.
I use your Upload Files [GH] action. It worked great with removing spaces, I tested that. Does your special characters include apostrophe? If yes, it did not work with my server. What should I do?
Thank you,
Nilubon

Hi Nilubon,

There are a couple of options that might help. There's a Make Safe option that should do it - but looking at the Joomla! code I'm not certain about that. If not the Slugify option should handle pretty much any string (see the original docs here).
