Thanks Otto42
Lunarpages mentioned they upgraded some components on my shared server. I also have another account with them (on which WP runs fine) and the differences are:
(WP-broken:)
Kernel version 2.4.21-47.0.1.ELsmp
MySQL version 4.1.21-standard
cPanel Build 10.9.0-RELEASE 118
(WP working:)
Kernel version 2.4.21-37.ELsmp
MySQL version 4.0.25-standard
cPanel Build 10.9.0-RELEASE 79
The PHP version is 4.4.4 on both. Any idea of what might be the exact root of the problem ?
Thanks again,
Andreas
P.S. I ‘ll give them a few more hours and then switch hosts if I have to. After 3 phone calls and 4 emails, Lunarpages support is really disappointing.
