Hello everyone. I am new with the templates. Just a quick question, please. I bought a template in Envato market 4 years ago, with the slideRevolution 5.1.6 pluggin. I updated to wordpress 5.5.3. at some point.
Now the pluggin is not working, nor the site, probably for one of the updates (not sure if because of the wordpress). It says that:
Fatal error: Uncaught Error: operator not supported for strings in /home/u917843485/domains/pablovelasco3d.com/public_html/wp-content/plugins/revslider/includes/framework/base-admin.class.php:71 Stack trace: #0 /home/u917843485/domains/pablovelasco3d.com/public_html/wp-content/plugins/revslider/admin/revslider-admin.class.php(465): RevSliderBaseAdmin::addMetaBox(‘Revolution Slid…’, ‘’, Array, NULL) #1 /home/u917843485/domains/pablovelasco3d.com/public_html/wp-content/plugins/revslider/admin/revslider-admin.class.php(72): RevSliderAdmin->addSliderMetaBox() #2 /home/u917843485/domains/pablovelasco3d.com/public_html/wp-content/plugins/revslider/admin/revslider-admin.class.php(44): RevSliderAdmin->init() #3 /home/u917843485/domains/pablovelasco3d.com/public_html/wp-content/plugins/revslider/revslider.php(165): RevSliderAdmin->__construct(’/home/u91784348…’) #4 /home/u917843485/domains/pablovelasco3d.com/public_html/wp-admin/includes/plugin.php(2255): include(’/home/u91784348…’) #5 /home/u917843485/domains/pablovelasc in /home/u917843485/domains/pablovelasco3d.com/public_html/wp-content/plugins/revslider/includes/framework/base-admin.class.php on line 71
Please, do you know if I should undone one of the updates for having the site working again?. It´s just a minute, I´m having big troubles for this, and I have no knowledge in web design unfortunately.
Thank you very much for your time
