Saving changed links (internal & external)

Hi there,

I didn’t work on my website for several months, meanwhile changed the theme, and now came back to ‘Sydney’.

I did all updates - wordpress/themes/plugins - and now I’m trying to get in again.

I installed following plugins:

Child theme configurator, cooke notice, instagram feed, limit login attempts reloaded, page builder by siteorigin, quotes collection, quotes shortcode and widgets, really simple ssl, si captcha anti-spam, sydney toolbox, tinymce advanced, updraftplus - backup/restore, wp maintenance mode, wp subtitle.

Several questions came up, as some things have changed. I would like to start with the links.

“Open page on new tab”: Although I always tick the box, with some links it works (tick has been saved), with others it doesn’t work (tick hasn’t been saved).

I don’t know if it’s relevant but every time I open a post to edit it, this notification is shown:

“Failed to load plugin url:

Hoping to get some help…

Many thanks in advance.

Best regards,


The mentioned file might not present. You should contact the plugin’s author.

Does this issue happen whenever activating all plugins or particular one?
