Hi Marta!
We would like to solve the problem, but do not understand exactly what the problem is.
What does it mean: “We have included a form input Product Tabs but leave us size 0px.”?
Which form do you include? What size is 0 px?
What does it mean: “This does not happen but your plugin installed.”?
Can you send us more exact description or an URL or screenshot, where the problem can be seen?
Thanks in advance! I hope after clarification of the problem we can solve it.
