 * When I try to activate the plugin, I get a server 500 error. I turned on detailed
   errors and when I try to activate the program, I get this information:
 * PHP Fatal error: Call to a member function getValue() on a non-object in G:\PleskVhosts\
   myshadowtechnologies.com\gremlinsbaseball.com\wp-content\plugins\wysija-newsletters\
   core\base.php on line 1499
 * I would love to use this plugin if I can get it to work. Any help out there?

 * Hi,
 * Can you delete and re-install the plugin via FTP? If that doesn’t work, your 
   server may not have enough memory, in which case you will need to contact your
   host.

 * I ran into the same error message, but my problem was the naming of the plugin
   folder.
    I renamed the folder to **mailpoet** (wp-content\plugins\mailpoet\) 
   which led to the error message. My solution was simply to rename the **mailpoet**
   folder to **wysija-newsletters** (wp-content\plugins\wysija-newsletters\).
 * Maybe this is useful for somebody.

 * Hello, I installed “mail poet” plug-in, via FTP
    The installation was ok, and
   it worked for a month. Some days ago, I found this plug-in disabled, and when
   I tried to activate it, I get “…\core\base.php on line 1499” the host mem_limt
   is 128mb what’s wrong? Thanks in advance
