Hi Everyone,

Following a Joomla and K2 update (and change of server location), K2 is not generating contents in the src and cache folder in the backend. After many forum searches and fix attempts, I am still puzzled about why this is not working.

The problem is as follows, I write an article and add an image via the image tab. I have a success message upon save and I see a record enter the K2 item table. The image will not process and display. The image is not uploaded to the src folder, nor processed by the cache. Images can be uploaded via the server image/K2 media interface but they will not attach to the article.

I’ve checked the sever configuration (all PHP items are fine, including GD2). I’ve checked the caches with main Joomla cache disabled. I can upload to Joomla and the article image is fine. I’ve checked the === issue (no problem - already updated). I’ve check post_max and upload_max (all fine). I’ve inspected the code via Firefox developer tools (all fine). K2 writes to the database so I cannot get an error in the developer options of Joomla or the logs (a green, success message). I’ve trebled checked all permissions and they are set correctly.

I’ve disabled plugins and switched them on one by one.

Finally, I’ve shifted the site to a development area and upgraded PHP to version 7 and the problem persists. All old items and images display correctly. I’ve also tried changing themes.

Are there any K2 and IIS web-server incompatibilities?

Hi Fotis, thanks for getting in touch. Yes, no problem uploading via the media manager.

I’m not sure if this adds anything more to solving the problem but I cannot upload an avatar image to the K2 user profile. Still, nothing in the error logs and I get the success message as though everything is fine.

I can also successfully add attachments via the Attachments tab and they display on the article.

After looking at the param paths (image v attachment) both are structured in a sensible manner.

After looking at everything (including checking absolute paths to the server cache/log and testing), I’ve tried reinstalling K2 and downloaded Joomla, unzipped and copied over the files in case something is corrupt. Still no luck.

The image is entering the param (I can see it through the POST option) but it’s just not doing anything inside the K2 cache/src folders. I’ve updated to PHP 7.1. Frustratingly, everything else is working absolutely fine throughout the site.

Is there a particular trigger that starts the image creation in the k2 cache folder?

Thanks

Hi, thanks for getting back in touch. I think it’s IIS 10 and Server 2016. It was working pre-upgrade. I did update the server/IIS too though. In fact, K2 has been working impressively until now.

Thanks. Part of the issue is that I keep getting a success message and therefore, no errors write to the logs. The K2 media section (and browse to server) work fine. Sadly, the thumbnail generation and multiple image sizes don’t trigger leaving the src and cache empty. I have full debugging turned on and developer level logging but no issue is being reported. I’m going to try a rebuild as a next step. I’m using GD2 (not GD) - would this cause any incompatibilities? I was also wondering if using paths with \\ (possible seeing the first \ as an escape?) may help solve the issue. I discounted this though due to attachments working properly.

Thanks Fotis. All logs are clear. Any pointers about where to look will be helpful.
