I am still not able to prevent my history details from disappearing, after shutting down OPERA (54.0.2952.54)
And that is exactly what I want ! To keep the history details.
Can anyone tell me what alterations to make?
Opera does not offer an option to delete its browsing history on exiting the program. So there is no setting that you could modify.
Would you mind answering @leocg's question please, otherwise it is difficult to provide further assistance.
At first glance I could imagine that your history file(s) has/have become corrupted. To generate new ones please follow these steps:
Close Opera.
Go to the directory \Your Opera-Path\profile\data\
In this folder, rename these three files (for example by adding .OLD) :
History
History Provider Cache
History-journal
Run Opera.
Opera will now create new and hopefully intact history files. Visit some websites, and check via CTRL+H that your browsing history isn't empty. Then close Opera and open it again. Was your browsing history kept?
