hm.
according to the error message, there might be something in the custom_bbcodes (line #0 "append_custom_tags()"):
Code:
Call to a member function query_read_slave() on null on line 279 in /local/sites/sitehtml/includes/class_bbcode.php
#0 /local/sites/sitehtml/includes/class_bbcode.php(241): vB_BbCodeParser->append_custom_tags()
#1 /local/sites/sitehtml/includes/class_postbit.php(345) : eval()'d code(13): vB_BbCodeParser->__construct(Object(stdClass), Array)
#2 /local/sites/sitehtml/includes/class_postbit.php(345): eval()
#3 /local/sites/sitehtml/showthread.php(1097): vB_Postbit->construct_postbit(Array)
#4 {main}
any idea?
