Problem with cache

[Thomas Hop]

Hello,

Recently we have been experiencing an issue with the .css cache of our community. For example, today we woke up to the forum looking like this:

We know we have a handful of custom applications, but these haven’t changed in a while, is there a possibility a new update causes this problem? Or is there some place (log or someting else) that can show the origin of the problem? We really don’t know where to look.

Thanks in advance.

Kind Regards, 

Thomas

Are you sure everyone sees this? Otherwise it would just point to a browser loading issue, which is quite common. Browsers are getting very “aggressive” with caching, so even resources that weren’t loaded successfully are kept in this state for some time. 

If everyone sees this I would start by using the browser developer tools to see which resources are failing. That might give an indication.

Also are you using any caching on your server at all? This may be worth checking. Things such as template disk cache could cause this too if things are not being written efficiently

This was really a problem of the cache of invision. All users (also fresh / incognito browser) had the problem. After Clear Cache in AdminCP the problem was gone.

We will check this first!

We checked with the hosting company. There is no caching enabled on the server. Do you have a clue where we could look to find out how this happened?

Please disable 2 factor authentication or enter the answer within the notes for this. We can then take a look, however as the issue is no longer present, we may well not see anything. As mentioned, the cache was not written which usually would be template disk cache and issues with writing to the server. In these cases we would generally advise switching away from template disk caching
