I am sorry Toine, we had an issue with the v3.1.2 getting published in the plugin directory. The latest version is now v3.1.3 and it should resolve the fatal error.
Hi Toine,
Thank you for bringing this to our attention. We have released v3.1.2 which should resolve that fatal error. If the problem persists, let us know!
Hi @mondalaci, We are sorry about the issue you experianced. There were a couple rounds of getting this resolved, but it should not be completely resolved in v3.1.2.
