Since yesterday, I’ve noticed some strange glitch when launching my website.
They disappear after a moment and I guess it’s just a loading issue.
By the way, the fonts are not shown properly: serif instead of sans serif.
I’ve already checked the Parabola font settings and tried the basic checks (deactivating and updating plugins). I’ve tried updating WP to 5.7 but it didn’t solve the issue either.
I don’t know if that may come from the Parabola or Serious Theme plugin.
However, note that the mobile version is OK (right font displayed).
