I can see how to install the debugger, a sticky post in this forum. But I can't see how to upgrade.

I have upgraded PHPEd to the latest version, and whilst running PHP 5.5.12 under Wamp on Vista, the Project Settings Wizard gives me the message
Warning: (-13) sub-minor version of the installed debugger module (7.5.3) does not match the clients one (7.5.10)
You may want to update debugger module to version 7.5.10


Can someone point me to the documentation, please.

Debugging works on some projects, but not all. It worked fine before the upgrade.

There's some info at http://www.nusphere.com/kb/technicalfaq/howto_install_dbg_module.htm

Thanks. but that is about installation, not upgrade. I couldn't get it to work.

I kept changing things, and eventually it did it automatically.
