i removed the plugin and reinstalled it. did not resolve the issue.. it is still giving the error when I put it back in.
For permissions i set the permissions to 777 and still would not save. Getting error below - I have other site on this same server that i can save successfully
Refused to set unsafe header "Connection"
mAjax @ vertex.js:1458
save @ vertex.js:3552
sa.children.(anonymous function).onclick @ vertex.js:3489
If you were using an older version of the Image and Content Fader, you may need to fully remove the plugin before installing the updated version, as there have been some necessary file name & location changes that the WP plugin updater doesn't handle correctly.
As for the theme options not saving, there are only 2 things that would cause that:
1. The options file needs to have writable permissions on the server, so that the admin can actually write the changes (vertex.json in the theme folder - minimum of 655, some servers need 755 or 766 - on rare occasions, 777 may be needed)
2. If it's not a permissions issue, then it's likely that your server is configured to block self-referencing URLs, which is a very rare issue, but has happened a couple times. That is an issue that you will have to get your host to help with, as it is a server setting, not something in the code.
