Thanks for your very prompt and helpful reply. I will investigate Stream.

You need to expand the folder ‘public_html’. Under it, you should find your WP root folder and then a folder called ‘wp-includes’. Expand that one too. You need to check the folder within it called ‘js’ (and all sub-folders). For good measure, repeat this process with the folder wp-content > plugins. Permissions need to be 644 at a minimum, or higher. Also check that you are shown as the ‘owner’ of these folders – your FTP client should show you this info. Have you tried deleting the problem page and re-creating it from new?

Incidentally, if you follow the link you quoted (http://cse.google.com/cse/cse.js?cx=3666861910616905:3axwej-lkhd) you get an error report from Google that says: “Your client has issued a malformed or illegal request.” That will pull WP up in its tracks. It’s kind of steering me towards the plug-in…do the makers have a support site?

lotusleaf9: That is looking like some sort of plug-in error, at a guess. Can you try deactivating the visual composer plug-in, then trying to edit just using the standard/native WordPress edit function? What happens if you do that? Firstly, does your error disappear and second, is editing possible? Also, FTP to your site and check permissions on the ‘js’ folder (and any sub-folders) within Wp-includes. You need to try and narrow down the source of the error so you know which specific area needs looking at.

You should be looking for any line that starts ‘Failed to….’. What happens if you just use the normal ‘edit’ link instead of the ‘edit with visual composer’ link?
