First, log out of wordpress, clear your browser cache and cookies, restart your browser and then try again. If that does not do it, restart your internet modem. If that doesn’t work, have you tried a different browser to see if that works?
2. Adobe Flash Player ActiveXÂ
- From your Desktop, click Start -> Run and type appwiz.cpl and press Enter
- From the Add or Remove Programs list, select Adobe Flash Player ActiveX and click Remove
- Now simply download and re-install the Flash Player again
3. Change a Setting
The /uploads folder in /wp-content needs more relaxed permissions than the rest of your site generally in order to allow the WordPress software to place images in there.
