I'm working on a Chrome browser page extension which worked properly until today.
For some reason I can't seem to reload the unpacked extension: it does reload without complaints, but when I try to use the options page only the extension name is shown as a caption - the HTML of the popup itself is not shown.
When the options popup is shown and I click on View Page Source (which doesn't always show -???), an empty tab opens (with a '1' in the margin).
When the options popup is shown and I click on Inspect, the expected HTML is shown, the options.html and .js are shown in Sources.
I've copied the HTML from that window and pasted it to the
W3C Markup Validation and this says "no errors or warnings to show".
From googling, I'm under the impression nobody else seems to have this issue.
What's going wrong here?
And how can I see this?
Regards,
Bob
