I appears you are running a custom SP theme and have not updated the CSS for WP 3.6.1 changes with the ui dialog.

Take a look at the codex here. http://codex.simple-press.com/codex/installation/changes/theme-and-templates-5-3-0/ where it lists theme changes.

Especially the part about popup dialogs.

it is strange.

I updated it to the new theme, and when i log in and click the image, the image shows correctly. But when i log off and click the image, it’s still blurry. can you double-check this? 

What Simple:Press theme are you using please?

If this IS a custom theme, are you sure you updated ALL of the ‘dialog’ bits that needed it? If it is NOT a custom theme – have you updated that as well as the main SP?

Thanks for the reply.

Yes. this is a custom theme. What i did was 

1.download the new updated default theme. (1.2.3)

2.customize the theme from scratch

3.change it to the new customized theme.

It means, i didn’t use my previous customized theme since changes were minor (like icons etc)

and i am using the most updated SP version. Simple:Press Version 5.3.3

can you tell me how to double check things?

Brandon gave you the link to the changes.. verify its in the theme…  a quick look and I can see you still have z-index of 100 vice that page that says to change it to 1… for example…

you are running a theme called joon-theme-2 which did not start from one of our core themes…  just verified that all our current themes have the z-index of 1 where as yours has 100…

Hi thank you all for replying.

that is really strange. i tested this in our local server

1. Because of your suggestion, I have re-downloded the NEW default theme at https://simple-press.com/download-themes/

2. I didn’t customize it but just changed the theme to Default 1.2.3

3. the problem still exists. screen is blurry when logged out, but it shows images correctly when i am logged in.

question:

1. this means that I have to check the code after I download the new theme?

2. when i change the theme it says “please wait” and it doesn’t change fast but have to click twice to change the theme. it means parts of the code is lost??

i am just confused, am i the only one facing this problem? 

thank you very much for your help. I really appreciate it.

Why don’t you email me your Simple:Press theme CSS file (or php file depending on how you constructed it) and let me take a look at it. You can send it to support at simple-press dot com.

OK – just seen the files you sent and they are identical to our default theme file so no problem with the CSS being current. And I assume you are using the most recent version of Simple:Press – correct?

So – do you have any other WordPress plugins installed that performs this lightbox type behaviour on images in posts? Could it be having an effect in the forum page?

I am quite confused how this is not working… or how its different for guests vs users…

but since its your own theme, in joon-theme-2.php, change either:

line 1776 to

z-index:1;

or line 1679 to

z-index: 200;

Excellent. Mr.Papa’s solution worked. I tested both, both works

I don’t know why this problem occurred. I’ve tested this in our local server after deactivating all plugins – but the problem didn’t go away. 

maybe other people are experiencing the same thing?

Thank you though. z-index solution worked!

No, others are not experiencing the same issue… the codex article on the changes (the ones in the default themes) are working as is… unfortunately, you are the first that had an issue with them…  and I dont really know why.

I experienced this issue too after upgrading. Caused by WP-Minify because I had not updated the “ignore” list of js and CSS files to suit the new SP plugin.

yes, wp minify tends to mess up javascrpt that is already minified…  thanks for the input…

This problem has occurred again after 3.8 wordpress update and simple:press update (default 1.2.4) –

I don’t think it is a theme conflict because I tried with Twenty Fourteen Theme and it doesn’t work.

but it works after I deactivate all of my addons for simple:press

can you please investigate this issue?
