firstly i tried installing woocommerce pluging directly and it failed.
Then I tried installing it ( woocommerce Plugin ) manually it got installed but it failed while activating.
after activating the website crashes and shows :
THERE HAS BEEN A CRITICAL ERROR ON YOUR WEBSITE.
similar issue occur while installing some other plugins & theme
Was your website already showing errors before attempting the manual plugin installation? Because if so, you should try to remove the broken plugins and themes first before attempting a manual installation. A manual installation on a working site should not fail like this.
@agarwalsons first thing to do is deactivate some plugins, try activating woocommerce again, then repeat this process until you find the plugin(s) causing woocommerce to fail.
If your site was showing errors before the woocommerce failure you’ll need to fix that first. You could use the same process, remove themes and plugins, then start activating them one at a time until you see errors to find the broken/corrupt plugin or theme.
