I have the following problem. I checked the forums and I tried to change permissions but still got the same result. After installing nopCommerce, I developed a new slider plugin. Firstly, It worked. After a while, It shows me the following error. If no one accessed the website, I got this. If I restart the application pool, It works normally for some time and then the same result. Can anyone get this before?
I added the following screenshot for this error.
