I've recently installed Photoproof. So far everything's fine. However, I'm struggling with replacing the existing Photoproof logo with my personal one.
I couldn't find a solution working for me neither in the respective blog entry , theme documentation  nor existing support forum threads.
I've installed the cited Safe SVG plug-in. I've creating the logo with Adobe XS, exported the SVG and pimped that with SVGOMG. Next I've uploaded the logo, which worked. However, afterwards my custom font used I've in the logo is gone. Is that maybe because I used a local font (with my personal handwriting?). Instead the logo uses now a default font (e.g. Times New Roman?). Last but not least, the logo shows up only on two of my pages, where dark pages are (e.g. standard album page 'with tag filter'), but not where black text should be (e.g. standard contact-ii page or page 'Home'). I'm aware I might have to add also code to CSS, but yet don't know which? I can send screenshots, if there is a secure way.
My (maybe incorrect) laymen understanding of SVG logos were, the SVG file itself just contains the vector data, while the embedded XML code contains whatever is necessary to draw the lines, while within my CSS file, I can address these SVG content and format it with.
I'm puzzled. Maybe I'm simply too stupid to add it correctly. Is there any (non-freak-)HowTo I can follow which is idiots safe? I can code, but haven't planned to become an CSS master in order to add a simple logo. ;-)
Thanks in advance for an advise what and how to do it.
