We just upgraded our servers from 8.5.2 with the extension library installed to 8.5.3 FP1 with the upgrade pack installed. It looks like the extensions library is running correctly, from what I can tell in the server console, but for some reason all my xpage applications are giving me a HTTP 500 error.
I have tried to create a just a very basic xpage just to see if it was something else that failed, but that did not work.
I am at a loss of where else to look for this error, right now we have a few of our websites down because of this. Any help or suggestions would be great.
Thanks.
**Edit: I figured it out. There were remnants of the original ext library that were causing the issue.
