I will try to help you make this thing better.
1- After install there are no options in admin.
2- There is no admin layout to publish, I have to add a button in the navigation to publish there. I expected to have an admin section to post from there and edit posts.
3- When I go to publish there are 5 blank categories, so categories are not working. I expect to have a category just for the blog that no other user can use that to post questions.
4- There are no comments, but there is a comments link that links to nothing. If there are no comments in your free version, why do you include a comments link for articles that does nothing ?
5- After publish I get redirected to /user/xxxx/articles and I see there “Recent articles by user” and everything is inserted three times, I see each post three times. So the plugin is triplicating the content inserting it in the database in a bad way.
6- When I publish something, each article gets an image inserted by default and an horrible style having post floating over each other. Why is that image inserted if I did not add any image ?
7- There is no way to add an image to the post, it just accepts external URL for images. I expect to add my own images uploading them from the post editor.
8- After the domain, the plugin adds // for everything. Example: domain.com//user/xxx/articles
9- All the published content is not counted as activity, so in my profile or in the recent activity, nothing is shown.
10- I want to see the complete post, not just the title. You stripped everything, added a BLOG POST IMAGE to everything, no content to read and just a read more and a comments link. The comments link does nothing and the read more takes you to the actual post.
You added a mouse over text preview that is awful, the content should show there, not just a title…
11- When viewing a post, if I click the avatar of the author, it takes you to something like this: domain.com/blog/3/blog_post_test/user/xxxx
Why are you linking like that the avatar ? it should link to the normal user URL, your plugin does not have to change the normal links for a user.
12- If a post has an error and can’t be found, there is no possible way to edit or delete, it will stay there forever, as the post does not load, I can’t delete it or edit it to fix it.
This is for your free plugin I tested in 15 minutes.
Now, the premium one is the same, but it has comments ?
Man, make it free again, lets fix all the problems, I will help you to debug everything and once you probe everything works and give good support, add premium versions with extra functionality or charge for custom work around your plugin.
For now this is not even alpha, has tons of errors and charging for it is not a good idea.
I am here to help, so if you want to take this to the next level, let me know.
