Q:

Error while Installing moodle 3.0.3+

the problem I think is because I retried installation of moodle on the same database, when I remembred that I did'nt create another database I just deleted all its tables and redo the installation but it gives me these errors.
PS: I tried to edit the file config.php, I did'nt find it, apparently Moodle did'nt create it while the installation ( I don't know if it means that there is a problem or not) 
Debug info: Error code: codingerror
Stack trace:

Thank you.

Thank you so much,
I made an error while installing moodle, since I reinstall it everything is okay now. 
For the problem of default theme I didn't have the file config.php in the folder moodle/theme/clean I added it and the problem is resolved. 
Thank you again :)
