Unfortunately i’m using a plugin that doesn’t support the WP excerpt metabox but do generate an excerpt in the posts. I tried adding something like the example shown here but i was getting two “read more* that i couldn’t get rid of. I did a fresh install (its the only way i know to solve WP issues) and will give it another try tomorrow.
My little brain is totally fried now, will update tomorrow how far i have come. Thanks !
