Cannot upload some files

No i am using a custom setup. At first i tried to install the cms version 1.8.10 but i cannot install it due to an error which i have previously posted in another topic(Need Help to install Xibo on ubuntu). So i install 1.8.9 which install smoothly.

I check with the report Fault and all are passes and also i have enable debugging option and duplicate the error and collect the logs.

and here is what i found in the log as a fault

|3848|a37f3b3|8/15/2018 23:07|WEB|/fault/collect|GET|Loading 1. All Objects = 0||DEBUG|
|3849|a37f3b3|8/15/2018 23:07|WEB|/fault/collect|GET|Install Fonts called with options: {"invalidateCache":false}||DEBUG|
|3850|a37f3b3|8/15/2018 23:07|WEB|/fault/collect|GET|CMS font CSS returned from Cache.||DEBUG|

Thank you.
