Hello,When a user signs in to the frontend and clicks on "add new item", we get this error:"Unfortunately there were no suitable nodes available to serve this request." (Normally I only get this error on timeout, but in this case it happens immediately.)Everything else with K2 is working great, just not this feature. My site is hosted on the cloud, and I spoke to the support tech. He says that the function is breaking Apache and causing a "seg fault" error.Also, he said something about a nonexistent URL, permissions error, 500 error, and rewrite rules, but finally said the cause was the "seg fault" error. Can anyone tell me what may be happening and how to correct this. I really need this to work.Thank you.
