Hi Bluepark,

I think you are using the Rich TextEditor php version 8.1.

Issue 1

Can you show me the full steps to reproduce this issue on demo http://phphtmleditor.com/demo/? If needs special content to reproduce it, please post here too.

Issue 2

What custom  Internal Links you are testing? can you show me the full code of your  custom "\richtexteditor\config\staticlinks.xml"? So we can test it directly.

Issue 3

I will report the path problem and your fix code to the development team, thanks for share the info. 

Issue 4

Please try the way below to disable the mobile layout.

open /richtexteditor/scripts/loader.js ,

and remove this line :

skin = "phone-lightsilver";

Regards,

Ken
