The changes in the options.txt file do not work

Since version 1.0.5 my interface has become very small, the settings do not help me, I decided to increase the interface through the options.txt file, it did not help me, but before I helped to version 1.0.4, I just changed the point gfx_guiscale_offset: 0 to 1. Solve this problem, it is impossible to play.
