I have a Chronoforms5 form where I want to redirect to another site but when I save the form the 'meta HTTP-equiv="refresh"' line gets changed to 'm-eta'. Any suggestions how to stop this?
Thanks for your suggestions. It was the RSFirewall component but it didn't need disabling which would have taken away the protection from hacks. It needed an exception to be added to skip JS protections for the Chronoforms5 component
The post at https://forum.joomla.org/viewtopic.php?t=772074 from 2012 is quite old but describes a similar problem where the solution was to disable the RS Firewall plugin.
I suggest upgrading Joomla and all third party extensions to the latest versions and if that does not fix the issue, disable third party plugins one by one (especially extensions like Regular Labs ReReplacer etc) to see if the issue is associated with a particular third party extension.
