Different users submitting same CRED form overwrite each other’s posts

Symptoms

The issue occurs when two different users submit the same CRED form at the same time. This causes one of the posts to overwrite the other and only one post is actually created.

Workaround

The problem will be fixed in the next version of CRED. In the meantime, the fix can be applied using this patch. 

Upload the files it contains to the embedded/classes folder and replace (overwrite) the same files.
