first of all when i click the nifty "go to the newest post" button read out that thread and go back to the forum all (and by all i MEAN all and any) posts are marked read.
with the back function of the browser to the forum and then on another thread's "go to the newest post" button the standard error "There are no posts since ur last visit" there is the following source error to read:
Warning: fetch(/home/turan/public_html/forums/../../scripts/ads/): failed to open stream: Success in /home/turan/scripts/inc/phpAce/AceTemplate.inc on line 33
Warning: fetch(): Failed opening '/home/turan/public_html/forums/../../scripts/ads/' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php:/home/turan/public_html/forums/../../scripts/inc/:/home/turan/public_html/forums/../../scripts/inc/phpAce') in /home/turan/scripts/inc/phpAce/AceTemplate.inc on line 33
hopefully this ain't the result of some kind of hack, just to let u know.
