DedeCMS weaves dream background login verification code error or does not display

It is common that the CAPTCHA input is clearly correct but the prompt is incorrect, or it is not displayed at all. Talk about several reasons for this situation:

1) incorrect CAPTCHA prompt due to incorrect upgrade operation of dede version program

2) better space the configuration of gd library in pho.ini in new space

3) the website space is full

4) caused by transferring data directory specifically to version 5.7

5) the problem of setting the permissions of / data/session directory in the program

6) clear the browser's cookies and restart the browser

7) the network speed is not good, another time, wait for the network speed to try again!

8) website program error, re-upload installation

The reason for the error or non-display of the login CAPTCHA in the background of dede Weaving Dream has been found, so now let's summarize the solution.

1. If it is caused by the transfer data directory of version 5.7.

Please change the file / include/vdimgck.php this file also calls the file in DATA can also change the path, with this / / data to your current path.

2, after consulting the data, we know that session has not been cleared, go to the data/session directory, and delete all files except index.html.

3. If it still doesn't work, see if session has write permission. If not, add write permission to "internet Guest account". If Linux, the directory permission is set to "777".

4. Set the php.ini of the server: open the php.ini file to find it; session.save_path = "/ tmp" is rewritten into session.cookie_path = / extension=php_gd2.dll; to remove the semicolon in front of him.

5, check whether your space is full, the test method is that you can upload a file in FTP space at will, there will be a prompt, you can contact the space service provider.

6. Remove the CAPTCHA directly: open login.php to find:

If ($validate=='' | | $validate! = $svali) / / be replaced by: if (false)

Then, remove the specific HTML code of the following verification code from the template dede/templets/login.htm:

CAPTCHA:

Or: in the [CAPTCHA Security Settings], it is said that the modified save is actually a modification of the datasafeinc_safe_config.php file, which is a configuration file.

For example: $safe_gdopen ='1, 2, 2, 3, 5, 6; this is where the CAPTCHA is turned on in the system. There is an one-to-one relationship with the CAPTCHA Security Settings interface.

Therefore, if we want to close the CAPTCHA at the backend (if the CAPTCHA cannot be entered correctly, the GB library is not supported), we only need to open datasafeinc_safe_config.php and delete the 6 in $safe_gdopen = '1jin2, 3, 5, 5, 6;. You don't have to make tedious settings.

7. Modify the vdimgck.php file of the include folder to modify the following paragraphs

/ / Session save path $sessSavePath = dirname (_ _ FILE__). "/ / data/sessions/"

Change to / / $sessSavePath = dirname (_ _ FILE__). "/ / data/sessions/"

After the revision, it does not work when it works, and this is also the case when it is changed back. If you change the DEDE background path to the default DEDE folder, there will be no CAPTCHA errors.

Finally, if the above methods are not applicable, then you can reinstall the corresponding version of the program, and then transfer your css and image files, template files, and upload folders. Finally, restore the database.
