You can fix the web server error with a change in the Apache configuration.

Did you set right permissions for your data? try it with executing the bash script from here, please.

I haven' tnoticed that the skript changed slightly. so with new skritp it seems to work (at least over mobile phone).

However as fo rthe apache i can not find those lines in any of the htaccess files or in the apache config file. i will need to revisit the site on mOnday from work to see if the error is still present.

site can be normally accessed from mobile phone and from my father's home but i still get the access forbidden from work when i try to access folders or open the manual files. but i can actally login to the owncloud and even administer it without any issues..

Can you tell us the forbidden message and perhaps the log content, please?
It can be that your employer has got specific firewall rules. You are allowed to do only specific things there. Ask your IT in the company. Every company has got his own security rules...
