So I have been using SignEdit since about 1.6 and it hasn't caused me issues, other than if I needed a dependency or some other plugin caused the error, but today It was working fine, then I stopped the server to add more plugins. These are the same plugins as I used (Long story short: my HDD/hard-drive reset 3 times, I'm on my 3rd starting my server from scratch with same plugins as I had before) in 1.6. I currently (about 10 mins ago) updated to 1.7.2 CB to see if it would fix the issue. But no, still erroring. It says "v3.3.2 is the current/latest version" and my error says "Out of date?," and I do not understand this at all. Please help 😃!

[16:36:58] [Server thread/ERROR]: Error occurred while enabling SignEdit v3.3.2 (Is it up to date?)

Yes I see it says "...Metrics..." but I have had the plugin metrics before and it still did the same thing.

The issue was caused by an outdated Metrics class. Now that it's updated, the plugin should work just fine.
