Thanks for your help. It is simple if there are no new ads, people will not find new material, so they stop using the web or enter and exit quickly so the bounce rate increases and implies less retention.
My biggest concern is with smartphone users, as they cannot right click paste. It turns out that 70% of our ads, due to the sexual nature of our website, are made from cell phones and are regularly texts that they had previously saved and are only copied, pasted and new photos are uploaded.
Could you help me with something else. Could you try to remember which Osclass Core file should be modified, I really appreciate that. This unforeseen came out after updating to Osclass 4.3 since it did not have this difficulty before.
