Having problem using certain bulletin program

[sixthhokake]

For my website, I'm using a bulletin program called Zeroboard.
I'm not sure how many people use this, but currently, I faced some problems.
I cannot upload any files by posting articles (even files that are less than 1 mb.) After attempting to upload, it automatically logs out the member.
About two days ago, there has been an update on the program.
So I changed it back to previous version, but it still doesn't work. One of the members on my website told me that he cannot even log on.
I assume that this is security issue.
Have any idea what's going on?

We don't officially support 3rd party scripts, you can try seeking help from the script creator. I see you have updated to intermediate, did you do this when you were having the issues?
