You were right. I discovered that the problem is with the form I had in the sidebar. For some reason, when you put a contact form there, sea as the sea, gives that failure. I have tried another topic and it does not give that problem. What can I do to put a contact form in the sidebar without that flaw?
The plugin is “Gravityforms”. And I have the latest version. With other themes does not give any fault, only with yours. I understand that I can try to use another one but that forces me to use two plugins for the same thing. At the moment I have removed it but I would like to have the possibility to use this plugin with your theme without this failure.
