It’s coming from this CSS rule:
@font-face {font-family: 'GE SS'; src: url(//:) format('no404'), url('fonts/ge-ss-med.ttf') format('truetype'); font-weight: normal; font-style: normal; font-display: swap;}Note the invalid CSS property value:
src: url(//:) format("no404")It’s in this CSS file in particular: https://www.fmp.ae/wp-content/themes/jarida/style-rtl.css?ver=0.3.1601827998
So it appears it is a bug in the Jarida’s CSS. The AMP plugin should be stripping out that invalid CSS (which we’ll look into), but the underlying problem is with your theme. So I suggest either patching the theme to remove that rule or contact the theme author to fix.
