can't access admin.php anymore
I haven't touched this site in 3+ years. My client uses it daily to update his class schedules, etc.
Suddenly today we can not reach admin.php to even attempt to login.
Warning: unlink(/cmsAdmin/data/settings.dat.php.597874aa4e70d8.52616479-temp.php): No such file or directory in /cmsAdmin/lib/common.php on line 235 file_put_contents_atomic: Error renaming over /cmsAdmin/data/settings.dat.php: (at common.php line 357 in function file_put_contents_atomic)
Here's the link http://www.bigironchl.com/cmsAdmin/admin.php
Any ideas where to begin?
