WordPress IOS app | Invalid Data Error with Untangle

If you utilize the Untangle Filter distribution and run into problems connecting to a self hosted WordPress site via the IOS App WordPress such as Invalid Data then here is the fix.   The problem is caused by the Intrusion Prevention Module.   If you open this modules settings and locate Rule 3827 usually found on page 96,97,98 or 99, you need to simply uncheck the block option.

Error may look something like this, can appear when you are syncing content or when you are trying to setup the app initially.

That is it,  I have found some users turn off the entire intrusion prevention module to get the app to work but overall just disabling the one rule is preferable as the module itself provides excellent protection for you network.
