When I try to install the plugin, this is the error that I get.

The plugin does not have a valid header.

Please advise. Thanks, Sandra

are you talking about the core simple press plugin? or some of our add on plugins?

if the former, please indicate how you uploaded the plugin to your server…

The one that is called simple-press.

I am trying to set this up for a client on a site that I lease to him. My goal is to use the forum as a way for him to communicate privately with his consulting clients and share drawings, etc…..

Your service was recommended by wishlist membership.

Thanks, Sandra

that’s the first part of the questions…  but how did you get it to your server?  ftp? wp plugin installer with our zip?  other?

I loaded the plugin through the “add new” section of the website through the plugins area.

and you did it with a file called simple-press.zip downloaded from here?

yes, I just downloaded the plugin today when I purchased the silver package.

okay…  can you try re downloading it again just to make sure it wasnt corrupted the first time…

but first, delete the current one from your server… either through ftp or the wp plugins list admin panel…

Ok, I will let you know what happens. Thanks, Sandra

worst case, if that fails, remove the plugin again…  and try extracting from the zip on your computer and upload the resultant simple-press directory (and all sub dirs and files) into wp plugins folder and see if that gets it going…

please let us know…

I just downloaded the zip from the server and installed on fresh set up… worked fine, so nothing with the file itself…

Ok, I just tried redownloading and resetting it up again with the same result. 

I am trying to add this plug in to a active website. Is that the problem? Is this a theme needing its own separate domain? I wanted to somehow tie it in to the wishlist membership login site for the clients consulting clients….

Please let me know. This is the first time I have tried to use simple:press.

Thanks, Sandra

Nope… active web site is fine…  no domain, just part of wp like you are doing…

yes, works well with wishlist member (what we use here)…

not sure why its giving you headaches…

did you try via ftp like I suggested?

Do you have a more detailed directions of what you want me to do?

are you not familiar with ftp?  would be hard to explain that process…

but WordPress plugins are stored in a folder on your server…  typically, /wp-content/plugins

on your computer, take the simple-press.zip file you downloaded and extract it on your computer…  you will end up with a folder called simple-press…  in it are a bunch of directories and files…

using your ftp client, upload directly to the server you are trying to install it on…  in the plugins directory I told you about above…  upload the simple-press directory and everything in it…

then go to the wp plugins list and try activating it…

but first, remove the failed attempt using the wp installer…  I dont have any real ideas why its not working for you – lots of installs that way…  its part of wp, not the plugin…
