You are right, Louis, is the E version, the theme is realized with the version of E 0.16.999.63789 , sorry
Every week there are changes in the default theme of E, also logically make such changes in the themes that I do.
In some distros this logical system to be more updated, no problems, others to be more outdated there are problems.
I'm sorry, so sorry, really, but until it is updated E ( ? ) in PCLOS and to avoid problems, currently no more themes will adapt to PCLinuxOS...
