when I complete a transaction I also get the following error:

Hi there,
Looks like you’re having some issues with caching. Memcache is a type of caching and it looks like it’s negatively affecting your user “Session” with Give.
Here’s a few items to look into:
1) If you have a caching plugin, disable it while testing. If that resolves the issue, reach out to the plugin author about it. But let me know what they say as well.
2) What host are you on? Some hosts have very aggressive caching. Reach out to them about the issue as well.
3) If you could post a link to your System Info for me to review that’d be great. Go to “Donations > Settings > System Info” for that.
Let me know what you find on those three items and we’ll work it out from there.
Thanks!
Hi Matt,
Thanks for quick reply.
1) I don’t have any caching plugins enabled. I
2) I am using TSO Host as my hosting https://www.tsohost.com

Hi there,
So a couple things stand out:
1) You’re on a Mutli-site environment so what I’ll suggest below might need to be applied at the Root install
2) The System Info shows that you have PHP Sessions disabled, that’s definitely the source of the problem. You can either ask your host to enabled them, or if they won’t, do #3
3) You can use an alternative method for your donor sessions. Simply add this to your Root Installs wp-config.php file:
define( 'GIVE_USE_PHP_SESSIONS' , false);
Let me know how that goes.
