Yes, you said that several times. We got that loud and clear. But you were asked by IPS staff to RESPOND AGAIN to that ticket if the issue persists and is apparently not caused by third-party code. Now please do that, as three people in this topic have advised. Adriano tried his best to help you here through the forums, but even he now suggests to go through a ticket as the issue apparently cannot be identified from a distance.
And yes, tickets might take several days. Not hearing back about non-critical issues for 28 hours on a weekend is perfectly normal.
