Image was not able to get Liked! maybe blocked ?

For a while now i keep getting the error "Image was not able to get Liked! maybe blocked ?" for maybe 95% of the images i'm trying to like. Together with an error on the Instagram page, leaving me with the choice of reporting the image and a few other things but not showing the post itself) A week ago all was fine, didnt change the quickstart.py or anything else. Left 1 or 2 days inbeetween trying again, but still the same error :( any ideas? Maybe try to include some timer between liking the posts?
If that might solve the problem, could you give me a hand with implementing?

My quickstart.py code:
`# imports
from instapy import InstaPy
from instapy import smart_run

insta_username = '******'
insta_password = '********'

comments = [':P',
':)',
'^^',
'o.O']
session = InstaPy(username=insta_username,
password=insta_password,
headless_browser=False,
disable_image_load=True,)

with smart_run(session):
""" Activity flow """

session.set_relationship_bounds(enabled=True,
potency_ratio=None,
delimit_by_numbers=True,
max_followers=7500,
max_following=3000,
min_followers=25,
min_following=25,
min_posts=10)

session.set_do_comment(enabled=False, percentage=100)
session.set_comments(comments)

session.set_user_interact(amount = 3, randomize = False, percentage = 100)
session.set_do_follow(enabled=True,percentage=100)
session.set_do_like(enabled=True,percentage=100)
session.interact_user_followers(['**********'],amount = 50, randomize = False)

Thanks a lot :)
