Subresource Integrity (SRI) Manager

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

Share of active installs on each version of this plugin · 100% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

   in the age of page-caching (wp-super-cache) and minification/consolidation of scripts/styles (autoptimization), this probably needs to be hooked in after all that gets done otherwise the hash generated won’t match. Ideally, this tests the consolidated minimized script locally even before it gets uploaded to the CDN to cover the pathological case that the script gets mutated at the CDN even before it gets it’s SHA hash done.

   Using the Plug in Yoco Payment Gateway by Yoco for credit cards and this plug in prevents Yoco from poping up and then redirects to the confirm order page like if it was an EFT when customer make payment via card. This prevents card payments. So I disabled it. This worked but im not sacrificing a function to kill revenue. There must be another way had another way just cant remember what the htaccess code was for this. This topic was modified 5 years, 9 months ago by techguysa. Reason: Author Rude

   I am confident your advice … Ensure your assets (scripts, stylesheets) were added using the WordPress API hooks, such as wp_enqueue_script(), and so on. … is sound. It is just a bit beyond my skill set/comfort level. This reflects my limitations, not the plugin. The SRI thing badly needs a solution that dunderhead WP users like myself can implement, and you seem to be the only one trying to address it. So, good for you. Much appreciated. I’ll do some learning and muster my courage and perhaps try again.
