Benjamin,
You’ve been asked this question a number of times, and it’s never actually been resolved despite the fact you keep marking it as resolved. We’re having this same issue. Its as if the single event view injects itself into any post query. We need a fix for this.
It’s not but I’ve fixed my issue. I’m still not sure of the nature of the problem, but I restarted Apache and everything went back to normal. I’ve never seen an issue like it before. No error reporting to be found. Nothing in the logs, nothing returned by php.
