Extension connector doesnt seem to be working

Hi, up until today zotero has been working well however today the extension seems to have just stopped. At first i thought i had run out of storage so i bought an extension however it hasn't resolved the issue. I then tried to re install the connector and it hasn't done anything.
The screenshot bellow is an example of what im seeing, i hope ive not done anything that is wrong just seems odd that it has just stopped working
