Fixed in 0.9.21.

OK, starting from next release the changelog tab will be available.

Full changelog is included into the PageSpeed Ninja package (file CHANGELOG).

Try to set “Merge embedded scripts” to Disabled (you can found it in the Minify JavaScript section of Advanced settings page).

This issue will be fixed in the next release.

The fix for this issue will be included in the next release of PageSpeed Ninja (hope to release it this week). Thank you for report.

PageSpeed Ninja shouldn’t affect admin interface at all.
Do you have enough free disk space?

I hope it will be ready in few days.

It’s because of “Minify URLs” option is enabled in the “Minify HTML” section of Advanced settings. Just set it disabled. We will fix it in the next release to don’t affect canonical URL.

The issue with spinner will be fixed in the next release (it’s related to flash-of-unstyled-text loading of google fonts).

There are three different ways to distribute optimized css and js files (see “Distribute method” in the Advanced tab):

1. Direct. In this case your webserver is responsive for compression and sending expiration headers.
2. Apache (there are two alternatives depending on installed Apache modules: mod_rewrite+mod_headers and mod_rewrite). Sending of precompressed files with expiration headers is made using special .htaccess file.
3. PHP. Sending of precompressed files with expiration headers is made by PHP.

You can use way #1 if others are not suitable.

Switch to Standard or Fast Simple HTML parser in Advanced tab of PageSpeed Ninja settings page. This issue is fixed in our dev build of the PageSpeed Ninja plugin, but there are a lot of other changes that should be tested carefully before release, so it may take a week (or more) to be released.

Currently it is not implemented, but we will try to do it in next releases. Could you post URL of the page with disappeared photo? Maybe there is an issue in our plugin that should be fixed (instead of disabling the page optimization entirely).

Thank you for feedback!

In next releases we will try to add new settings preset to reduce disk usage (with few disabled features: caching, image optimization, and loading of external resources) and possibility to choose preferred preset just after the plugin installation.

Do you have enough free disk space? (PageSpeed Ninja requires about 1.5 Mb)
