What is u’block’ error . How to correct it
Could you please elaborate this maybe with an example if possible so that we could better understand and respond to you.
Have a great day!
Unfortunately, and as hinted by @Kal_Lam , this could be a result of several things. This cannot be easily. The most common being a problem with your form. I suggest you review the XLS version of your form and identify if there are specific errors in it. This should resolve your issues.
