Strange error notice / .blcontainer

Hello,

the plugin works fine, but in the backend, I get this error message – what does it mean and how can I get rid of it?

.blcontainer .blitm { /* These are technically the same, but use both */ overflow-wrap: break-word; word-wrap: break-word; -ms-word-break: break-all; /* This is the dangerous one in WebKit, as it breaks things wherever */ word-break: break-all; /* Instead use this non-standard one: */ word-break: break-word; /* Adds a hyphen where the word breaks, if supported (No Blink) */ -ms-hyphens: auto; -moz-hyphens: auto; -webkit-hyphens: auto; hyphens: auto; }

Cheers,
Eric
