Update has caused my child theme css to stop working

Looking at the log, it seems that it is being includedhttps://prntscr.com/m6ye66 but your child theme has a space in the directory name, which may be breaking things accesspress-store child (themes and plugins are not supposed to have spaces in the names). Furthermore, your child theme style is enqueued twice.

Make a backup first, then rename your theme to have no spaces on it’s name.

Ot you can try to disable inline merging,
or you can select the option to inline all css and see if it works.

okay but why did it work fine until the last update?
How can i stop it from loading twice?

A lot has changed on FVM during the past updates in regard of CSS optimization, but I don’t think that there is nothing which could cause the the file from being enqueued twice.

The way to check it, is to momentarily disable CSS processing on the plugin settings.
That will probably fix the menu, but the css won’t be optimized.

Another option is to select the option to inline all css.

Alternatively, you can either:

a) Download the previous version and manually install it:

b) wait for more updates

c) Try another plugin, such as autoptimize.

how do inline all css? i see no option for that in the settings?

inlining css made no difference, ugh this is so annoying!

Like I said, a lot has changed on the previous updates.

You can remove FVM if it breaks things and manually download/upload an older version, or use the autoptimize plugin.

As for the older version of FVM, you can download it by replacing 2.5.4 with whatever version you would like.
