Can you hear that? – Neither can Eye.

This is just a heads up on what’s happening at this end.
Note: working locally with the Laragon server and creating a new WordPress theme.
2nd Note: really horrid to set it all up, and it all works well, BUT!

Working locally as I am, then your subject to your Internet suppliers erratic connection speeds, speeds that can be Zero! – Thus failing on a windows 10 machine.

Observations:-

1.) If the Internet fails (for whatever reason), then the Plug-in needs to be reactivated on the settings page:-

Text To Speech – Amazon Polly
Amazon Polly configuration
Source language: [ English ]
Enable text-to-speech support: [ ] <– this becomes unchecked, rechecking it again and it’s all working as it was.

2.) Since the last update, version 4.0 [Oct 30th]: then this is being reported under the Bulk Update tag:-

Additional configuration
Bulk update all posts:
Warning: First parameter must either be an object or the name of an existing class in C:\laragon\www\writeOn\wp-content\plugins\insert-pages\insert-pages.php on line 187
Bulk Update
Functionality disabled in this plugin version.

I think that it means that the plug-in “Insert Pages” is interfering with your own AWS Plug-in. I don’t use this aspect of the voices plug-in, and the error doesn’t seem to prevent your voice scripts from reading text on the test website: which is all that I’m actually after. (So all’s well.)

These observations have been placed here for your information only.

Hope it helps – Jessica.
