Various problems and questions

Hi,
can anybody help me with these things, please?

1) Uploaded Images get their brightness modified automaticaly when displayed at dark themes, how to disable this?

2) I cannot change the standard Fontcolour of the WYSIWY get Editor, guess it's related to some standard Settings… I'am still able to modify this somehow using css?

3) Using Version 7.1.1 I was recently contacted by my Hosting Service, that I created several files with a bunch of GBs each, filling their Harddisk. Beside some very huge files they deleted on their own at the Servers temp folder (beeing called "ps7xsvmk" and "psdUnrkI") I also found the persistant cache to be unbelivable huge (close to 1GB) and a 4GB Backup File beeing created the Day I tried to delete old logfiles using the CMS tool. (i tried it twice, and the process never went through) Soo there probably Bugs with the logfile deleting tool and the persistant Cache.

4) I received 10 hack attempt E-Mails yesterday (see Below) Is there anything I should or can do?

Thanks for advice!

If someone try to use the GET code, there is a serious hack attempt.  Your ISP can do something to secure this GET code. Its server related. But the ocportal security has block this attempt. 

1- Some browsers differ in how Gamma settings in PNG files are displayed. Putting them through a PNG optimiser usually helps. You also may be thinking about the fade effect used in IMG_THUMB.tpl/the img_thumb CSS class. I'm sure other users can go into more detail if needed.

3- The stats delete thing is definitely a bug. We'll fix, but you can workaround it by manually emptying the 'stats' table. As for the persistant cache, I can check it out but I'll need you to send a random sampling of the persistant cache files to chris@ocportal.com so that I can see what particular thing is running out of control in there.

3 - It's just fixed. See here: Persistant Cache filling up

Simply upgrade to the latest version of ocPortal and that's it

Regarding 1) (the faded images), you can turn off the option to automatically fade image thumbnails by going to this section of your Admin Zone: Setup » Configuration » Theme options » General.
