redhatx2Nevermind, I found a way to change it back using the chrome developer settings. It seems in the option menu of the paper_latern theme for switching themes, only the second option in the menu executes the onchange js code. By changing the value of the option tag on the second option to basic and then clicking on it, I was able to force the theme to switch.
Problem solved. A posting by redhatx2 in Dead-i member page guided me to a solution.
Thank you buddy! I've been trying to revert back for several months now. Lol.OMG THIS WORKS!!!
In details, if you are using chrome go to the page where you are supposed to change the theme. Right click over the selection box for change the theme and click "Inspect". After that you have to know some html and change the value of the second option tag to "basic".
