  • The studio swears that you need to use the theme from the library of support. In this case, if the problem is only in the previewer, then instead of trying to fix it, it is better to refuse to use it. He's not needed. You can still roll back to 1.5. version of the studio. About version 2 glitches for a few questions a day here are asked. - JuriySPb ♦
  • And how to roll back to 1.5? And yes, it's only in the viewer. - RAPOS
  • How to roll back, I do not know) Probably you can search for the installer of the required version ... Well, or to score - after all, if it's only a viewer, then this is a great opportunity to refuse to use it) - YuriySPb ♦

    Well, it’s much simpler than html) And in any case, the viewer is wild, WICK buggy. Piss off with him. He very often shows the wrong. Especially something more complicated than the left-indented text field. - Yuriy SPb ♦

    It is quite possible)) That's when they get used to being without a viewer, then I will refuse))) Now I probably need to roll back)) - RAPOS
