I have tried everything, even the beta version but i dont know what is going on, if is the wordpress version or something else, in fact if i post manually from the post, the plugin tweet it with hashtags but if i change something in there too, like removing HT or something it publish it anyways (without the changes), so i guess is some problem with plugin itself, all the problemas started when i upgraded it to the newest version, i also deleted the database and reinstalled, i was really happy with this plugin because it is exactly the thing i need it, and beta version has many great features BUT if it the plugin can automatically set the hashtags its going to be a problem. Thanks. If need it i can provide acces to the site so you can check it out.
