Hi Frank,
did you add any new plugins before starting to see this problem?
Please disable all non GD plugins and try again.
Let us know,
Thanks
p.s.
It is totally useless that you install all this plugins in an attempt to speed up your website: WP Performance Score Booster, WP Super Minify, WP Super Simple Speed, Speed Booster Pack
1st of all because they are not compatible with GeoDirectory, second because using WordPress, plus X Theme, plus 45 active plugin and 20 unactive plugins, means working on an inevitable disaster waiting to happen.
If you want your website to be faster change theme and reduce the plugins to the bare minimum. There isn’t a general rule saying how many plugins installed is ideal, but the less is always better.
