You’re the first user of 3.5.1 to report this problem, it is most definitely JavaScript-related and quite possibly caused by the theme you are using.
I have developed a work-around that consists of changes to 2 different files that you will need to download and replace:
ssba_admin.js (from the js folder) https://ge.tt/api/1/files/9p7gyCg/0/blob?download
and
ssba_admin_panel.php (from the inc folder) https://ge.tt/api/1/files/4wgxyCg/0/blob?download
You will need to clear your browser’s cache so that the JS changes take full effect (hold ctrl and press F5 for some browsers, best pressed many times!).
Please enter exactly the following into the replacement ‘Include’ option that will be shown:
buffer,flattr,linkedin,facebook,pinterest,twitter,google,reddit,diggit,stumbleupon,email
Feel free to remove any of these and rearrange them, but they must be separated by commas with no spaces. E.g. you could also enter:
flattr,buffer,linkedin,twitter,facebook,pinterest
Any questions/problems just let me know.
Please make backups before making changes if you can. If you’d like me to login and take a look just let me know – [email protected]
Thanks,
David
