Hi Steve,
2 problems:
1) the 2 add-ons installed are very very old (+12 months at least). You should always keep both core and add-ons at their latest version.
You should never update the core and not the add-ons or the other way around.
Now they are so old, that auto updates will not work (they are still using the old auto update system that we changed in January).
You will need to download them from here: https://wpgeodirectory.com/support/members/ybmsteve/downloads and either update them manually via FTP (extract them 1st). Or using a plugin like this one: https://wordpress.org/plugins/easy-theme-and-plugin-upgrades/
2) W3 Total Cache is not compatible with GeoDirectory. You should deactivate all it’s component, clear the cache and lastly deactivate and delete the plugin.
Only GD Booster or the WP Super Cache + WpAutoptimize combo will work with GeoDirectory.
Let us know if that helps.
Thanks
