Cache problems – Images are disappearing after a while
– The sliders are disappearing after a while, then pushing the Refresh Cache button brings them back.
– The images in the sliders are disappearing after a while, then pushing the Refresh Cache button brings them back.
– The sliders are disappearing after a while, until the Joomla’s cache isn’t cleared.
Note: You can follow the instructions in here, even if you are not sure if this is your problem, because it won’t cause any trouble. It might even prevent future conflicts.
Then go to the Smart Slider’s Settings → Cache, and click on Refresh Slider. After this go to your System → Clear Cache, and delete all the cache files, so your website would have the new datas for the slider.
You might also need to change the loading order of the system files, if there is some other extension’s plugin modifying the loading. You should go to the Extensions → Plugin manager, and pick system at the – Select Type – filter.
Click on the ordering.
Reorder them, in Joomla 3.x by clicking on the little squares before the checkboxes, and drag ‘n drop them, that the Nextend Library would be on first place, and in Joomla 2.5.x change it’s ordering number to 0, and if you have other zeros, change all other orderings to +1 from the original.
If you would still have problems with your cache, check out this part of the documentation.
