Hi,
that's a great gallery and i will buy the full version - but I got one question before:

Sometimes in the Event-View (I use Event - Image List as my Event Layout) a single picture is left blank. After refreshing the site everything works correct again. Is there a known issue? What could I do, to improve that?
At the moment I am testing on my local server so I can't provide a link.

Best regards,

Reinhard

Sounds like the usual problems with a weak server configuration. I guess you're getting randmon HTTP 500 errors? Please have a look at the servers error log. That should reveal the reason.

I can't reproduce the problem at the moment, but I am very sure that this is the corresponding error, it occured some times in the past:

[05-Oct-2015 09:44:11 Europe/Berlin] PHP Warning:  file_put_contents([...]\xampp\apps\joomla\htdocs\cache\com_eventgallery_images\Test6\nocrop104150604-011.JPG): failed to open stream: Invalid argument in [...]\xampp\apps\joomla\htdocs\components\com_eventgallery\helpers\vendors\class.jpeg_icc.php on line 183

I found another error - but only three times in the past few days, so, it is probably not worth looking after that:

[05-Oct-2015 09:43:29 Europe/Berlin] PHP Notice:  Undefined index: foldertype in [...]\xampp\apps\joomla\htdocs\administrator\components\com_eventgallery\models\event.php on line 145

Best regards,

Both are only warnings. They do not cause HTTP500 errors. But they can cause invalid images since the message is part of the image data.

Please open the network tab of your browsers developer tool and watch out for HTTP 500 messages in case you see blank images. You need to open this tab before you load the page in order to see the requests.

I just bought the Extended version and installed it on localhost, and I got the same problem. I am sure the blank picture is related to that warning:

[08-Oct-2015 15:55:28 Europe/Berlin] PHP Warning:  file_put_contents(...\xampp\apps\joomla\htdocs\cache\com_eventgallery_images\Test\uncrop200150604-wiesenfest-006.JPG): failed to open stream: Invalid argument in ...\xampp\apps\joomla\htdocs\components\com_eventgallery\helpers\vendors\class.jpeg_icc.php on line 183

But dont worry about that, I will go live with my new installation the upcoming weekend - perhaps the problem is gone when it's live.
It's a great gallery anyway and I will come back and tell you if it works on live-system.

Best Regards
Reinhard
