Hey Nuajan,
That is odd, have not see that exact error before… If you want to submit a support ticket I can help you debug this very uncommon one-off issue (be sure to refer to this thread if you do). It looks like it is definitely related to your environment which can be hard to simulate across the millions of possible different configuration scenarios.
On a side note it can also sometimes still be related to other plugins/themes even when they are disabled. I noticed you just registered your account “Nuajan” at www.ads-software.com. Not sure if your a new WP user or not, but this is not really an encouraged practice to give out 1 stars without trying to get help first. Developers spend allot of free time on these plugins and require the help of the community to help work through these issues… I’m not really sure this warrants a 1 star… I hope you would reconsider your vote…
Thanks
