Hello,
Sorry for the problems with the text issues when trying to change the colors. You may want to make sure that you have the current version of the BoldGrid plugins. Make sure they are updated. If you’re still having the problem after checking, please check to see if there are other plugins that may be conflicting. You should be able to click on the orange control handle when hovering over text. Click on the “hamburger menu” (it looks like several horizontal lines), and then click on Font. The color option is on the right. Here’s what it should look like:
If you continue to have the problem, please provide information about the version you’re running as well as any error messages you might be seeing.
