The website is www.gtotc.org. I used Cornerstone to build the site and it worked fine until recently. Now, the home page opens but all the links result in a URL not found message. I called support on the hosting site and they say the problem is with Cornerstone. I saw the similar problem on the support page where the solution was to reset the permalinks. However, I don’t know how to reset the permalinks.
Please help!
