hi

just delete both temp_CACHED* files in typo3conf/ and thats all - cache 
is cleared.

If after clearing the cache manually the problem will still exist then 
check the line in temp_CACHED_ where the problem was.

In you case it was:
/home/deafhub/public_html/typo3conf/temp_CACHED_ps94bc_ext_tables.php on 
line 2774

Try to figure out what is bad in that line and what extension possibly 
is making this error.

Then go to typo3conf/localconf.php
find $TYPO3_CONF_VARS['EXT']['extList']
and remove from this list the extension that is making problems.

Clear the cache again manually.
