Warnings on activation

[shackep]

I am running wordpress 3.5.1 as a multisite. When I enable this plugin I get these warnings on the /wp-admin/tools.php?page=flowsplit_tools page:

Warning: fopen() [function.fopen]: Unable to access .../public_html/wp-content/plugins/flowsplit/flowsplit.php in .../public_html/wp-includes/functions.php on line 3508

Warning: fopen(.../public_html/wp-content/plugins/flowsplit/flowsplit.php) [function.fopen]: failed to open stream: No such file or directory in /home/pixelplo/public_html/wp-includes/functions.php on line 3508

Warning: fread(): supplied argument is not a valid stream resource in .../public_html/wp-includes/functions.php on line 3511

Warning: fclose(): supplied argument is not a valid stream resource in .../public_html/wp-includes/functions.php on line 3514

Warning: Invalid argument supplied for foreach() in .../public_html/wp-content/plugins/flowsplit-master/includes/tools.class.php on line 175

This last one is what I get when trying to use the shortcode. I see all test versions when I preview the page. The short code elements are invisible.

ok, something wrong with the loop getting the array from transients.
I will provide a check before this event.

It's updated but only with an if statement.
Have you tried to generate som content to the transients before checking at the tools page?
Have you tried to activate the plugin in just a single site in the network?

Great it works now!

It still has the last warning on the flowsplit admin panel: Warning: Invalid argument supplied for foreach() in /home/pixelplo/public_html/wp-content/plugins/flowsplit/includes/tools.class.php on line 195

Hi, I'm getting the a similar warning on my admin page: Warning: Invalid argument supplied for foreach() in /home/content/77/8077777/html/paws/wp-content/plugins/flowsplit/includes/tools.class.php on line 195

Also, I can't seem to get the desired images to display in my sidebar. I've tried to paste the code in an enhanced text widget that supports shortcodes, but no luck.
