Hi!
I am pretty sure that the error message refers to the Synfony framework used in FreePBX and not to the big and bulky iSymphony…
re:
I did the same mistake as you a few months ago. Lorne (@lgaetz) was kind enough to point out the mistake…
re:
And as Andrew (@tm1000) pointed out in that same thread, you cannot remove that Symfony, FreePBX would crash…
Have a nice day!
