5. Notes and Common Issues

Plugin

We create a plugin and install it on your website to optimize wordpress source code, according to the principles of safety and protection of your original website:

  • We do not directly edit any css, js, php .. files on your hosting but generates new css, js files based on the original resources of the website.

  • We do not make modifications in the database.

  • Plugin only works on the frontend and is disabled for logged in users.

To avoid errors, the following issues should be noted:

  • Please do not enable lazyload, merge + minify CSS + JS in themes & plugins like WP-Rocket, Jetpack, Smushit, Ewww-image-optimizer or from another plugin.

  • Do not enable Lazy, and Rocket features on CDN services such as Cloudflare, Godaddy.

  • After editing / adding / deleting css / js files, press the 'Flush All' button (Settings> Page Speed Optimizer ) to create new CSS & JS files. In case of directly inserting <style, <script tags, just delete the cache created by plugins like WP-Rocket, W3 Total Cache, ..

Your web is being cached?

Penci Speed Optimizer is not a cache plugin but you are activating a cache plugin like wp-rocket, w3total...If you are struggling to test the website and do not know if this error is actually fixed or not, you can add any parameter to the end of the URL to make sure that the URL has not been cached. ex: http://domain.com?xyz=1233434

Check the original

You can completely review the original version of the website because remember that Penci Speed Optimizer does not modify every file & database of the website.

Once your site is optimized, you can review the original version again by adding this parameter to the end of the URL ?nooptizpp=1. Example:

  • URL optimized: https://example.com

  • URL for original: https://example.com?nooptizpp=1

Note: Before sending us error feedback, please compare it with the original.

Some plugins can cause conflict with Penci Speed Optimizer plugin:

No. You can completely update the WP core, theme & plugin or even install a new plugin that does not affect or decrease the Pagespeed score.

Note: Some specific plugins will add new JS to the web that uses javascript variables that are shared through multiple <script tags, which can most likely cause JS errors. In case of JS error in chrome dev tool, please see the documentation for dev below.
