Cannot access Thread Logged In: EFU:R Leaving/Returning Posts

[Luke Danger]

When attempting to access the thread ( http://www.efupw.com/forums/forum/ma...g-posts/page83 ), I get an error message which is as follows:

[h=1]Internal Server Error[/h] The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@efupw.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

However, when I logged out I was able to access the thread normally. I got the above message both for Microsoft Edge and Google Chrome. It may be an error from the server updates as I have not used this account in a long time, but asking on the IRC no one else seemed to be having any problems.

EDIT:
Also occurred for this thread: ( http://www.efupw.com/forums/forum/ma...er-theme-songs ), but other old threads such as the Realmslore topics still seem to be functional for me
  ​EDIT 2: And now I'm able to access it, though it took some loading time. Original bug still seems to persist, however.
