#3 Allowing the Crown Jewel event to occur
The Crown Jewel event in Saudi Arabia was a major mistake. WWE received widespread criticism. Female wrestlers were not allowed to compete, and this caused a huge backlash, as a couple of days prior to the event, WWE had an all women PPV - Evolution.
WWE should have scrapped this PPV, but the WWE management were seemingly considering the financial losses. The PPV has tarnished the reputation of the company, and marred its image.

To make matters worse, they brought back the teams of Undertaker and Kane, as well as Triple H and Shawn Michaels. This match was unnecessary and was just made to attract the crowd.
The entire PPV was horribly booked, including Shane McMahon winning the World Cup. It was one of the worst decisions WWE has taken in recent times.
