Hi Linda,
Don’t know whether you still need any suggestions, but for anyone who wants to fix the following error:
“Activation failed: The filter extension seem to be unavailable”
NOTE: The following method works only when the plugin is installed using comopser. I apologize to anyone who install the plugin using WordPress admin.
Please follow the steps:
Step – 1: You already installed the plugin & cannot activate it. Navigate to wp-content/plugins/wordpress-seo folder using Terminal/CMD line/PowerShell.
Step – 2: Run the following command in your terminal
composer update
