If the MyFitnessPal site at https://www.myfitnesspal.com is not working, appears strangely formatted, or behaves in unexpected ways, we first recommend visiting our Announcement page to see if there are any major outages we are aware of. Additionally, you can check our Known Issues page as well. If there is nothing noted for the issue you are experiencing, here are a few steps you can try on your own to see if they help resolve the issue.
Currently, our site does not support "https add-ons" you may have elected to use with your web browser. If you've enabled such an add-on (such as HTTPS Everywhere) please exclude MyFitnessPal from the add-on's list of sites to see if that helps.
Sometimes, when we update our site, your browser may hold on to out-dated versions of some of our content. If this is the problem, it can be resolved by emptying your browser's cache. This discards old assumptions about how our site is designed, and reloads a fresh version of the site from our servers.
Please visit https://www.myfitnesspal.com/diagnostics/ in your web browser
Run the tests on that page. If they all pass, emptying your cache may resolve your issue.
Instructions are here https://www.wikihow.com/Clear-Your-Browser's-Cache
If you are using Internet Explorer 8 or later, please note that you should uncheck the "preserve data for favorite websites" option if you have MyFitnessPal favorited or bookmarked.
If you are using Safari 6 or later, the correct instructions are here https://applehelpwriter.wordpress.com/2012/08/02/how-to-empty-caches-in-safari-6
After emptying the cache, please quit and restart your browser.
If you are still having a problem, please send us an email and let us know what tests did not pass, what type of computer you use, the web browser you are currently using, if you've tried other web browsers and had the same result, and your MyFitnessPal username.
The option to reach us by email is located at the bottom of the FAQ/Feedback screen in our mobile apps, and in the top right area of our Help page on the website.
