Thanks for the fast reply, I actually successfully managed to previously upload the .svg file using a variation of your mime uploader to the functions.php file.
The problem squarely lies in the fact that the vector .svg logo is resizing to 0 x 0 (natural 150 x 26 px) and I’m trying to work out which element is causing the img tag to reduce the vector to 0x0 pixels. Is this related to the visibility of the display:block in css?
you can see the problem yourself, this is for the xxx nite vibes domain, so the vector logo is simply xxxnv.com, with spaces between the letters.
i should also point out that we’re using the same set up for 2 other subdomains also running open-source classifieds wp job manager: see this sydney classifieds site here and for our melbourne classifieds where both appear to be displaying the vector ok — and both these sites are supposedly a clone of the main xxxnv.com domain — so im not sure why the vector is failing to show in the main domain? Is this a caching issue?
A friend suggested that perhaps I can enter the pure svg code as a workaround, but the div slicknav_brand tags don’t seem to allow it.
