Deleted plugin but posts still redirect to _gL(long string) before correct url

Hi, I migrated a Blogger blog to WordPress using the plugin, but later realized I wouldn’t be able to delete the plugin for redirections to work, but most importantly, that I would have to keep the same ugly permalink format of Blogger for all my new posts.

During install, I also run the php script to make post name equal to the Blogger original.

Anyway, I deleted the plugin and also reinstaled the theme in Blogger (thus, deleting the inserted code provided by the plugin).

However, in my WP blog, whenever I now click on the title of a post, it firts goes to myblog.com/post-name/_gL(and a long string of letters) and then goes back to the correct post-url.

Moreover, once I’m on any post, the browser bar showing the correct url (after the redirection), if I now click on the Site name (Homepage link), it also firts redicrecto to the site name + _gL(long string of letters) and then shows the correct home page url.

How can I get rid of these redicrections?

I already corrected the content of many of the imported posts into WP, and took me days, so I don’t want to re-import the Blogger posts and spend more days reviewing and correcting again the content.

Please help, Thanks
