Board Image Showing in Recent Additions

This is weird.  Notice the coin as a new addition in screenshot.  It's the obvious fake retrograde N that I poosted from a 2009 auction a few days ago.  I'm on my iPad and sometimes experience odd graphics caching issues on this website, but was this coin really in the Forvm coin shop?  You can see that I was even on this thread when it was displaying!

That is the exact same photo as in the thread above. I have never had the coin and it was never in recent additions. If you look at the coin photos in the screenshot, the Forum photos are compressed for fast loading. Any zoom and they get very mushy.  The Pompey coin photo stays sharp because it is not compressed.  Not sure what is going on here.

Depending on the device I'm using, sometimes coins posted in threads appear in the shop and vice versa.

Just sent Sorin a link to this thread.

I had this happen to me in the past and I posted about it.  But it hasn't happened in a very long time to me.

[Joe Sermarini]

I could understand it if the files had the same name. I don't believe there is anything in our code that a browser should legitimately interpret this way. 

Please let me know what device, operating system and browser you are using if this happens again.

I have never had the problem, perhaps because I have my browser cache sized at zero. I have a fast enough connection that I don't want to see old versions of anything to make loading faster.

It happens on iPhone 4S and iPhone 6 using safari, but never on chrome on my desktop.  It is more frequent if the loading is slow or my connection poor.

I occasionally have the same problem when browsing on my iPhone 6+ using safari.... Sometimes members avatars appear in the shop images also...  And occasionally pictures posted in the thread appear instead of avatars... It's pretty random but seems to be restricted to mobile browsing.

Sorin updated the board software and php software.  We are looking to see if this is a known issue for Safari and if there is a solution.  

I split this problem into a new topic because it isn't really related to the original poster's topic.

I notice there is only 3 columns of coins instead of the usual 4. Do some only see 3? I always have 4.

[Brennos]

I have 8 colums of coins

I guess it obviously depends on screen size or resolution.

This is not a problem with Forum. This is a known Safari issue and can happen on any website. It can only occur if you visit the site more than once in a relatively short period. As Molinari noted above, it will probably only happen with a slow or bad internet connection. Safari uses a capability called HTTP pipelining, which is intended to speed website loading by uploading multiple things at the same time. Unfortunately, when the connection is poor it can confuse an image from its cache with another image and display it in the wrong place. This is not something Forum can fix.

The following is from a tech blog website:  http://tech.vg.no/2011/12/14/safari-on-ios-5-randomly-switches-images/:

Since the release of iOS 5 we’ve received several bug reports about images randomly displaying the wrong image(s) on our front page for smartphones. It seems to be completely random and could affect any of the images, anywhere and anyhow. During one week we would receive anywhere between two and ten reports about this error. In the same time period we would do about 4.5 million page impressions (2.9 million of them from iPhone) on the front alone....Safari is the only browser to use a capability called HTTP pipelining.  HTTP Pipelining enables the browser to send several HTTP requests on the same connection before receiving the responses. It can even send new requests while still receiving an earlier response. Pipelining is still pretty new; Opera was the only browser that enabled it by default, Firefox have support that’s disabled and Chrome will support it in Chrome 17...What Safari does is that all the image(s) that are requested in the middle of a response end up containing the image currently being transferred. It also uses the cache headers of the same image that's being transferred, so if the cache headers (Expires/Etag) allows it, Safari will keep this image (with the wrong content), but with the right filename. Therefore a “soft” refresh without emptying the cache will still display the wrong image...There is no solution yet.
