I (foolishly) tried to enable an installed module whilst on my shared hosting. The site times out, which isn't all together unsurprising. However now I get this error message whenever I try and make any updates to the site (enable any modules, clear cache, run cron etc.)
Any thoughts as to the cause. Here is the error in full.
Fatal error: views_plugin_display::destroy(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "metatag_views_plugin_display_extender_metatags" of the object you are trying to operate on was loaded before unserialize() gets called or provide a __autoload() function to load the class definition in /home/xxxxx/public_html/sites/all/modules/views/plugins/views_plugin_display.inc on line 272
If it makes any difference it was the Metatag module I was trying to enable.
