Technote Details :: Cannot convert content to XHTML

When I try to submit a form that has the Convert to XHTML trigger applied, I get an error message:

Error Executing Tidy!

This happens because the trigger is trying to execute an external program - HTML Tidy - and this attempts fails. The Convert to XHTML trigger relies on an external library / program to perform the actual operations on the selected content. This error occurs due to several reasons:

1. The path you provided for the HTML Tidy executable is not correct.
2. The web server user does not have permissions to run programs on the server.

There are two solutions to this problem:

1. Check that you have specified the correct path to the HTML Tidy executable. Verify that the file exists on disk in the specified location.
2. Check the access permissions for the web server user: you must allow read and execute rights on the file and folder. On Microsoft Windows you must also allow execution rights on the cmd.exe file.
