Cannot reply to thread: Internal Server Error...

[clinchfield]

I've been trying since 07-11-19 to reply to the thread at http://ddisoftware.com/tech/printers/test-image-prints-poorly-(color-matching)/

... and I get the following:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at root@localhost to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.

I have been able to reply to another thread in that time. Is there an issue with the forum?

Anyone? Now I'm unable to reply in another forum. This happens in Firefox  and Chrome.
