Hi Toufiq,
thanks for answering.
As I wrote, after site crashed with wrong colors, header and menu out of line and many more after updating everything, I reinstalled a backup version which seemed to work mainly. (Only last menu field drops down cos my custom value for"#sp-header .sp-megamenu-parent > li > a" is ingnored by template.css)
So if I update Yamas, Helix, SPPB to their latest version or do any other change like toggle the compression of css or compiling scss to css .... the site totally crashes in weird presets/colors and more.
My nearly working config is:
SPPB 3.8.0 / Helix 2.0.5 / Joo 3.10.2 / Yamas 1.1.
I didn´t want to touch the site cos the coach expects to work on the content next week.
thanks
