Purchased the fortuna theme last week, very pleased with all I have seen of it so far….
One issue:
When I try to activate the Revolution Slider plugin I get the above error. The complete error message is…..

Fatal error: Uncaught Error: [] operator not supported for strings in /home/588/346588/public_html/wp-content/plugins/revslider/includes/framework/base-admin.class.php:71 Stack trace: #0 /home/588/346588/public_html/wp-content/plugins/revslider/admin/revslider-admin.class.php(572): RevSliderBaseAdmin::addMetaBox(‘Revolution Slid…’, ”, Array, NULL) #1 /home/588/346588/public_html/wp-content/plugins/revslider/admin/revslider-admin.class.php(73): RevSliderAdmin->addSliderMetaBox() #2 /home/588/346588/public_html/wp-content/plugins/revslider/admin/revslider-admin.class.php(44): RevSliderAdmin->init() #3 /home/588/346588/public_html/wp-content/plugins/revslider/revslider.php(162): RevSliderAdmin->__construct(‘/home/588/34658…’) #4 /home/588/346588/public_html/wp-admin/includes/plugin.php(1882): include(‘/home/588/34658…’) #5 /home/588/346588/public_html/wp-admin/plugins.php(164): plugin_sandbox_scrape(‘revslider/revsl…’) #6 {main} thrown in /home/588/346588/public_html/wp-content/plugins/revslider/includes/framework/base-admin.class.php on line 71

Any help / suggestions would be much appreciated

Thanks

Obviously some error in the plugin, you wouldn’t be able to activate the plugin though.
You are using the extended theme license for the plugin which means you can use it with the theme the only thing you can’t do is activate it as you don’t have a private key.
No worries, you don’t really need that anyway, you can always update to the latest version (if you really need to) by asking for it here in the forum. :)

If I understand your comments correctly, there are two issues here:
1. The plugin is throwing the error (this is what I suspected).
2. It will not activate anyway as I don’t have a private key, and presumably I cannot update to the most recent version either to see if that resolves the issue.
Are you saying that the slider can be used with the theme wityhout activation? or have I misinterpreted that?
If an updated copy of the plugin is available through the forum, then I would like to try the updated version to see if it fixes the error.

Regards

John

I’ve updated the plugin and the error has not recurred. It has also activated correctly. Many thanks for your help.

Regards

John
