I just fixed a significant bug that appeared in Q2A 1.5.4.
If you have it set to prevent low-rep users creating new tags, then it added an onclick attribute to the ask question button. However, Q2A 1.5.4 also added an event to the same button, creating a major bug where low-rep users could not ask questions.
My code has been updated to use unobtrusive Javascript which solves the problem. So make sure to update your code! Github repo is here.
