The TheoryTab main page seems to be down at the time of making this post, it’s throwing a 500 error on my end. Attempting to access the page using the drop down menu at the top of the screen gives the error.
Using Mac OS X 10.10 with Google Chrome.
I’m also getting a 500 error.
Windows 10, Google Chrome.
@bigyihsuan and @Threxx: thank you! Fixed late last night. Had something to do with the Tab of The Day.
