The website encountered an error while retrieving

Hi,

I was tinkerinng with color values in theme-options.php. I tried subsituting blue for diff shades. It didn't seem to have an effect. I tried on last color, and then I got:

Server error

The website encountered an error while retrieving http://www.xyzxyzxyz. It may be down for maintenance or configured incorrectly.
Here are some suggestions:

• Reload this webpage later.

HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.
I copied the theme-options.php file from the downloaded theme after I was able to access the page again using back arrows, the pasted it it fresh into theme-options.php, but I'm still getting the error message and now can no longer access my website.
HELP

 

I think you have done something wrong while editing.
Download theme again form members area and upload it.
If you are not able to access dashboard then you can upload theme through FTP.

 

Thx - fixed it by getting into error log in host site. Another question - on the homepage slider, I've uploaded a .png image that has a transparent background, but is showing as a white box around the image, rather than being transparent. How do I fix this???

 

Please share the link of your website.

 

I fixed the transparency issue but need a code snippet to get rid of the frame.

 

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.flexslider .slides {
border: none;
}
.flexslider {
border: none;
background:none;
}
