If you are having trouble posting messages on the forums, there suddenly seems to be a bug with using accented characters, including the euro symbol. If you use these characters, you will get an error message that says:
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 1245184 bytes) in /home/lee/public_html/assistants/forums/includes/utf/data/utf_compatibility_decomp.php on line 2
You just need to replace all accented characters with regular characters and you should be able to post. I'm not quite sure what is causing this problem or why it is just now happening.
