I have just upgraded to 5.0.3-beta-5-2013-04-28
In using IE10 a message comes up stating "Your web browser is too old. For this site to work correctly, we recommend you use a more recent browser.". The version of IE is the latest.
How can I turn off this particular message?
You are right, the version regex was faulty. You can fix it manually or comment out the line that reads
to disable the warning completely:
