 * Uncaught SyntaxError: missing ) after argument list
 * Hi,
 * On my test page [https://focusme.com/pricing-test/](https://focusme.com/pricing-test/)
   with latest update installed I get 3 of these errors in the chrome browser console
   and the font is wrong for the whole page. If you compare the fonts with [https://focusme.com/pricing/](https://focusme.com/pricing/)
   you will see how it should look (FVM plugin disabled on the live page).
 * Can you help?
 * Thanks!
    Jon
 * p.s. FVM is the most awesome plugin!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Funcaught-syntaxerror-missing-after-argument-list-2%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * I think you must have some other plugin, trying to optimize javascript delivery(
   async, lazy loading, defer, or whatever).
 * Something else is adding an attribute called `data-cfasync` to the generated 
   js file urls, which doesn’t exist on my plugin.
 * Please note, that you cannot have multiple plugins trying to do speed optimization.
   
   It not only become slower (double work), but it will cause conflict (double minification,
   etc).
 * You have to disable any other plugin or option, that merges and minifies js and
   css files, AND you cannot have other plugins trying to load css or js async, 
   or lazy loading them.
 * You can lazy load images though, just not css and js files.

 * You were absolutely right. Though I don’t have other optimizations enabled, my
   pricing table plugin was doing that for some reason in a function called prevent_rocket_loader_script.
   I have tweaked the plugin so it does not do that and will report it to them.
 * Thanks a lot!

 * The rocket loader they refer to, is from cloudflare:
    [https://support.cloudflare.com/hc/en-us/articles/200168056-What-does-Rocket-Loader-do-](https://support.cloudflare.com/hc/en-us/articles/200168056-What-does-Rocket-Loader-do-)
 * I recommend all these to be disable on cloudflare (if used), as these are mostly
   useless.

 * Thanks, I do use Cloudflare but already have this feature turned off as per your
   very helpful FAQ section. 🙂
