You need to keep plugins up to date, some of your errors are from old versions of some plugins.
I’ll get a developer to have a closer look too to give some pointers, but with all the non-GD plugins being out of date etc, the caching plugins etc.
Try deactivating all plugins you do not need, update the rest.
If you want a developer to have a closer look, confirm that we can de-activate anything non-GD to test.
