Hard time with pm

Good Morning:

Just recently I seem to have difficulty in replying to the odd pm here and ther: A couple of minutes ago I tried to reply to one - a fsx.cfg modification suggestion for another user - and got this response:-

Fatal error: Call to a member function buildAndFetch() on a non-object in/opt/webdocs/newsite/forum/hooks/wolf_replyIntoNewPC_link_membersEmail_c40835c23f43faa64997314fb1117192.php on line 88

It seemed a normal pm, nothing different from any one of the others I've sent over the years.

Any advice, please?

Thanks

pj

Edit: - it seems it did send the pm - but it also sent the ones that I tried to re-send after the first error message. It evidently didn't fail on each attempt, but didn't notify success!

Also - the introduction of a second font really screws up the post!

Thanks,

pj
