After upgrade, forumdisplay & showthread displays default style

[محروم.كوم]

just upgraded from version 3.7.2 PL1 to 3.8.3, this was my first time to upgrade and everything seemed easy enough and went great until i got to the template edits part

here i may have 'reverted, updated or saved' something wrong that has effected my styles


all of my styles have the default style as the parent...all but one looks ok after upgrade, for some reason one style reverted to default style, so i went in and changed the CSS back to all the settings i had before, thinking it would be ok

when i looked at the index page, everything looks fine, but when on the forumdisplay and showthread pages it is still showing the default style, all other pages seem to be fine too, it is just these two pages

any ideas what i need to do to fix this problem? __DEFINE_LIKE_SHARE__
