    hi maxd

    I was bought your extension and I was really happy for it. But other extensions cause a problem and I have to build my website from zero.

    now I try to upload and install your extension but somehow my extension installer doesn’t work. So I upload over FTP but xml files should be uploaded on extension installer at least I read like that

    so. question is can I install lightning just using FTP without extension installer (which is not working for me now)
    and how can I re activate my license for it? I will use it on same domain.

      Try to upload XML file to installer, it should work even if ZIP hasn’t.
      The license will be active, if the domain hasn’t changed.

        For some reason, I find it hilarious that in all of the prnootiomal pictures and videos for this thing, her face is shiny. Does the woman not own powder? Oh wait, that must be her motherly glow emanating from within~ she just has way more of it than the rest of us, because she is the best mother ever because she eats REAL FOOD.

    after installed the extension my site was down, and I had to disable the extension. The message on the site:
    Notice: Undefined variable: stheme_help in /home/naturallhome/public_html/system/storage/modification/catalog/view/theme/supertheme/template/common/footer.tpl on line 3

    After disabled the extension, the site is working without problems. Do you know what should be the problem?
    Thank you very much
