# html optimization breaks widget plugin

* I just installed Autoptimize and have been configuring and by and large love
it!
* I noticed however that one widget I use, based on this plugin: [https://wordpress.org/plugins/wp-tab-widget/](https://wordpress.org/plugins/wp-tab-widget/),
seems to not load.
* I began working through the instructions for excluding the plugin from js and
css optimization and worked through a variety of settings only to discover that
even turning off js and css optimization still left the plugin broken! Accordingly
I tested turning off html optimization and it started working again! Furthermore,
it continued to work if I then turned js and css optimizations back on without
any non-default exclusions.
* So, weirdly, it seems it’s the html optimization that’s causing this plugin to
fail to load, not the others. Unfortunately there’s not option to exclude a plugin
from html optimization like there is with the others so for now I’ve just had
to turn this feature off.
* Is this a bug? If so is there a fix coming? Is there a way to get html exclusion
added like the others so I could turn it back on but exclude this plugin? Any
help would be appreciated; thanks!

* No idea why that would happen I’m afraid. Can you enable HTML opt and then
1.
check the browser console for errors? 2. copy/paste the resulting HTML and put
it up on pastebin.com or a github gist for me to review?

* Browser console definitely has errors; the warnings below are there even when
the site works fine but enabling html optimization adds all the errors in the
below. Pastebin of html at [https://pastebin.com/6ppEmEX6](https://pastebin.com/6ppEmEX6).

* OK, so;
1. something (not AO’s HTML minifier) is removing quotes. this could
be the case if you’re using both W3 Total Cache & AO at the same time, in which
case W3TC’s HTML minifier is “forced upon” AO (a known bug in W3TC 2. jQuery
is not defined means you will have to ensure jQuery is not optimized or asynced
or deferred. 3. you’re also using Asset Cleanup which offers optimization features
as well, that might make things a tad more .. fragile as depending on configuration
there might or might not be conflicts 😉

* So, to make sure I’m understanding, it sounds likely to be the W3 Total Cache
known bug that’s causing this issue? If this is a known bug, is there a known
workaround?
* On 2 – will look into that.
* on 3 – The issue is there are page-specific unloads that I’m able to do in Asset
Cleanup which Autoptimizer doesn’t seem to enable. I’ve turned off all other
settings in Asset Cleanup though so that shouldn’t be an issue; I’m basically
only using it for page-specific unloads.

* re W3TC; only 2 solutions i.e. disabling HTML opt. or swapping W3TC for another
page cache plugin (I favor KeyCDN Cache Enabler or WP Super Cache).
