Thank you for the suggested actions to take.

However, though I followed them all the issue remains unresolved, ie. I cannot see the charging station icons nor site menu when loading chargehub.com.

I do not have this issue with any other WEB page including other sites which provide similar service as chargehub. Even more curious to me, as I've mentioned before, my son running the same OS on his desktop PC does not have the issue. When he loads chargehub.com with Firefox the site menu and charge station icons appear as expected.

I've attached an image of the chargehub map page.

What security software are you running? Do yo have the same issue using another Windows account? If you do not have another account make one and test.

Thank you for your thoughts/pointers.

I did what you suggested, and should have been obvious to me. I logged in as administrator, ie another account.

When opening chargehub.com in Firefox on my admin account it worked properly. I got the charge station icons and the site menu with options.

Also, thanks to your handle, it occurred to me that since I have a dual boot machine I could boot into linux and try firefox/chargehub there as an alternative. But no need.

Now I have to figure out what is different between my user account and admin account to fix the problem. Any suggestions in that regard are welcome.

If I check the Network Monitor then I see a lot of 404 errors for retrieving the "ChargeHub IconFont" as defined in this file:

• https://chargehub.com/css/styles.min.css

The TTF version appears to be available, but the woff and woff2 format give a 404 error for me.

• https://chargehub.com/fonts/ChargeHub%20IconFont.woff
• https://chargehub.com/fonts/ChargeHub%20IconFont.woff2
• https://chargehub.com/fonts/ChargeHub%20IconFont.ttf

So maybe contact the website and ask them to look into this.

Interesting observation regarding the ChargeHub iconFont. I will have to go back and compare settings between my user account Firefox and Admin account Firefox as regards fonts.

I will forward your info to chargehub as well.

And I have downloaded Network Monitor.

I appreciate your time and effort on this issue. I will report back any further findings for me and any response from chargehub.

I don't know whether those missing icons are coming from this font as other generic icons are still displayed.

Note that the Network Monitor is one of the built-in developer tools.

Thank you all for the support. Though the issue is not resolved I will pursue on my own for now thanks to the various help suggestions provided which give me a direction to look. I have alternate software to use in the interim.
