after updating your plugin today I got a whitescreen only on my plugins page in the admin. I changed your folders name to newsletter2 then and managed to login again. Now that I renamed your folder back to the original name again it wont let me activate it no more, it keeps giving me:
Warning: require_once(/Applications/MAMP/htdocs/csmlu/wp-content/plugins/newsletter/includes/logger.php): failed to open stream: No such file or directory in /Applications/MAMP/htdocs/csmlu/wp-content/plugins/newsletter2/plugin.php on line 70
Obviously it keeps looking for the modified folder. Is there a workaround to get it started again?
