At the moment I'm developing an extension SEO Hero for the Google Chrome browser. Every day takes a lot of energy, attention and effort.
I spend every day development. Extension of SEO Hero for Google Chrome and Canary browser is created and run in the browser. I pay the fee.
However, to publish the extension has not obtained and I work for publish.
At first I thought the first error:
No manifest found in package. Please make sure to put manifest.json at the root directory of the zip package.
The error has been corrected. Today met a new second error:
An error occurred: Failed to process your item.
the manifest.json: 31: 2: unexpected char.
I re-read documentation for correct the error:
- https://developer.chrome.com/extensions/manifest/icons
- https://developer.chrome.com/apps/about_apps
- https://developer.chrome.com/webstore
The error has been corrected.
Finally, I finished writing a code of extension and published SEO Hero for New York and World on the Google Chrome Webstore site.
