V 0.14 blinking vs v 0.13 that works

yooo super Jinx you solved that! may you please explain what have you done? what are differences between wled 0.14.b4 of https://install.wled.me/ versus https://wled-install.github.io/, just because they are named the same. I’ve never seen the website of your link before works! thanks a lot

Jinx linked me a github link with a perfectly working version of wled, without any blink.
