Hello expert,

Weeks ago I have installed PHP v.7 .
Since then I get many error messages at the top of all my Piwigo webpages.
Do you know how I can solve these problem-functions, so visitors do not see these ugly messages anymore?
Is Piwigo actually ready for PHP v.7?

A. Error messages:
Deprecated: Function create_function() is deprecated in c:\...\piwigo\include\functions.inc.php on line 2165
(13 times this message on 1 page!)
Deprecated: Function create_function() is deprecated in c:\W...\piwigo\plugins\AdminTools\include\MultiView.class.php on line 41
Deprecated: The each() function is deprecated. This message will be suppressed on further calls in c:\...\piwigo\plugins\GrumPluginClasses\classes\GPCCore.class.inc.php on line 270
Deprecated: The each() function is deprecated. This message will be suppressed on further calls in c:\...\piwigo291\include\template.class.php on line 293

B. Also, the plugin Piclens 3D-Wall of CoolIris does not work anymore (because of deprecated functions?).

Thanking you in advance for any useful advice,
Rolf
