For links2SD, please check the SuperSU app for a green "#" next to the Link2SD icon. if it is gray, or red, then that's why you are getting permissions issues on Links2SD.I disabled the SDSwap app and still have errors with Link2SD.
When going into Settings --> Accounts & Sync then pressing on the 'Google' Account, the next screen shows 'Sync error' below the Gmail email address. When going into that account, all items, i.e., App Data, Calendar, Drive, People Data, etc, show a date and time last synced. Not sure I understand why.
Also noticed shortcuts don't show on the default lockscreen.

Also, the Google Sync issue could be a number of things, I will unfortunately not be able to narrow that down without physically looking at your phone.
As far as the default lock screen, it is AOSP and I have no control over it as it comes built into android (and without serious modifications, of which I cannot do yet) so the lock screen can be replaced by WidgetLocker as shown in this video: WidgetLocker on AdvancedStock7 for LG Optimus Fx3 - YouTube
Please allow at least 20 minutes from the time of this posting for the upload to finish.
This is a video of me using WidgetLock (From the playstore. Latest version)
**Please note, I am running the latest version of AdvancedStock7.
