Howdy,
I am using Mantis 1.1.1 and PM 0.2.1 and I have uninstalled HTML Mail to trouble shoot a problem I was having with sending mail. The mail problem is now fixed, but I cant get HTML Mail to reinstall. I removed the files from the plugin/ directory, removed the entries from the plugins_pm_function_overwrite_table and the plugins_pm_dependencies_table.
When trying to install I get:
Install the plugin
Step 1 / 1: Register function : FAIL Conflict with ****ERROR****
Have I missed something?
