I have a page in WordPress using ckeditor as the editor.
I have inserted the following code:
[advanced_iframe securitykey="da39a3ee5e6b4b0d3255bfef95601890afd80709" src="http://xyz.com/Alphabetical_Listing_list.php" width="920px" height="920" scrolling="auto"]
Everything was working properly for weeks.
I added a few words before the iframe and updated. I now get the following message:
An invalid security key was specified. Please use at least the following shortcode:
[advanced_iframe securitykey="<your security key - see settings>"]
The security key is correct - I have checked it many times.
I reverted to a previous working version of the page, and the error now appears on that page too.
I have flushed the cache of the entire site.
I cannot explain it - I have also tried inserting the advanced_iframe shortcode in the html page rather than the normal wysiwyg part of ckeditor.
Any help would be greatly appreciated. This is such a smart plugin!!
