>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #888238. --> Reported by: [calbasi](https://www.drupal.org/user/318818) >>> <p>Hi,</p> <p>I couldn't upload any file because I get HTTP 0 error (An HTTP error 0 occurred.<br> /web/ca/upload/js). But in other drupal installations, in the same server, I can do it. The reason? I have devel module, without logs but with query time and memory info (the error is present with any of this options checked).</p> <p>Files are uploaded (you don't think it because you get the error, but after saving the node, you can see them). Is, then, only a annoying error, but not suitable for endless users).</p> <p>I've read this: </p> <p><a href="http://drupal.org/user/35821">http://drupal.org/user/35821</a></p> <p>When I uncheck these 2 options, I can upload files.</p> <p>Ps.: drupal core version: 6.16</p> <p>Ps.: I've got the error with devel 6.x.1.22 and 6.x.1.21</p> <p>Ps.: sometimes I get this web page<br> <a href="http://delaterra.net/web/ca/upload/js">http://delaterra.net/web/ca/upload/js</a></p> <p>{ "status": true, "data": "\x3ctable id=\"upload-attachments\" class=\"sticky-enabled\"\x3e\n \x3cthead\x3e\x3ctr\x3e\x3cth\x3e\x3c/th\x3e\x3cth\x3eSuprimeix\x3c/th\x3e\x3cth\x3eLlista\x3c/th\x3e\x3cth\x3eDescripci&oacute;\x3c/th\x3e\x3cth\x3ePes\x3c/th\x3e\x3cth\x3eMida\x3c/th\x3e \x3c/tr\x3e\x3c/thead\x3e\n\x3ctbody\x3e\n \x3ctr class=\"draggable odd\"\x3e\x3ctd\x3e\x3c/td\x3e\x3ctd\x3e\x3cdiv class=\"form-item\" id=\"edit-files-179-remove-wrapper\"\x3e\n \x3cinput type=\"checkbox\" name=\"files[179][remove]\" id=\"edit-files-179-remove\" value=\"1\" class=\"form-checkbox\" /\x3e\n\x3c/div\x3e\n\x3c/td\x3e\x3ctd\x3e\x3cdiv class=\"form-item\" id=\"edit-files-179-list-wrapper\"\x3e\n \x3cinput type=\"checkbox\" name=\"files[179][list]\" id=\"edit-files-179-list\" value=\"1\" checked=\"checked\" class=\"form-checkbox\" /\x3e\n\x3c/div\x3e\n\x3c/td\x3e\x3ctd\x3e\x3cdiv class=\"form-item\" id=\"edit-files-179-description-wrapper\"\x3e\n \x3cinput type=\"text\" maxlength=\"256\" name=\"files[179][description]\" id=\"edit-files-179-description\" size=\"60\" value=\"new_logo_organic_farming_en.jpg\" class=\"form-text\" /\x3e\n \x3cdiv class=\"description\"\x3e\x3csmall\x3e<a href="http://delaterra.net/web/sites/default/files/new_logo_organic_farming_en_4.jpg">http://delaterra.net/web/sites/default/files/new_logo_organic_farming_en_4.jpg</a>\x3c/small\x3e\x3c/div\x3e\n\x3c/div\x3e\n\x3c/td\x3e\x3ctd\x3e\x3cdiv class=\"form-item\" id=\"edit-files-179-weight-wrapper\"\x3e\n \x3cselect name=\"files[179][weight]\" class=\"form-select upload-weight\" id=\"edit-files-179-weight\" \x3e\x3coption value=\"-2\"\x3e-2\x3c/option\x3e\x3coption value=\"-1\"\x3e-1\x3c/option\x3e\x3coption value=\"0\" selected=\"selected\"\x3e0\x3c/option\x3e\x3coption value=\"1\"\x3e1\x3c/option\x3e\x3coption value=\"2\"\x3e2\x3c/option\x3e\x3c/select\x3e\n\x3c/div\x3e\n\x3c/td\x3e\x3ctd\x3e5.96 KB\x3c/td\x3e \x3c/tr\x3e\n \x3ctr class=\"draggable even\"\x3e\x3ctd\x3e\x3c/td\x3e\x3ctd\x3e\x3cdiv class=\"form-item\" id=\"edit-files-183-remove-wrapper\"\x3e\n \x3cinput type=\"checkbox\" name=\"files[183][remove]\" id=\"edit-files-183-remove\" value=\"1\" class=\"form-checkbox\" /\x3e\n\x3c/div\x3e\n\x3c/td\x3e\x3ctd\x3e\x3cdiv class=\"form-item\" id=\"edit-files-183-list-wrapper\"\x3e\n \x3cinput type=\"checkbox\" name=\"files[183][list]\" id=\"edit-files-183-list\" value=\"1\" checked=\"checked\" class=\"form-checkbox\" /\x3e\n\x3c/div\x3e\n\x3c/td\x3e\x3ctd\x3e\x3cdiv class=\"form-item\" id=\"edit-files-183-description-wrapper\"\x3e\n \x3cinput type=\"text\" maxlength=\"256\" name=\"files[183][description]\" id=\"edit-files-183-description\" size=\"60\" value=\"Contorno (2).jpg\" class=\"form-text\" /\x3e\n \x3cdiv class=\"description\"\x3e\x3csmall\x3e<a href="http://delaterra.net/web/sites/default/files/Contorno">http://delaterra.net/web/sites/default/files/Contorno</a> (2)_4.jpg\x3c/small\x3e\x3c/div\x3e\n\x3c/div\x3e\n\x3c/td\x3e\x3ctd\x3e\x3cdiv class=\"form-item\" id=\"edit-files-183-weight-wrapper\"\x3e\n \x3cselect name=\"files[183][weight]\" class=\"form-select upload-weight\" id=\"edit-files-183-weight\" \x3e\x3coption value=\"-2\"\x3e-2\x3c/option\x3e\x3coption value=\"-1\"\x3e-1\x3c/option\x3e\x3coption value=\"0\" selected=\"selected\"\x3e0\x3c/option\x3e\x3coption value=\"1\"\x3e1\x3c/option\x3e\x3coption value=\"2\"\x3e2\x3c/option\x3e\x3c/select\x3e\n\x3c/div\x3e\n\x3c/td\x3e\x3ctd\x3e4.48 KB\x3c/td\x3e \x3c/tr\x3e\n\x3c/tbody\x3e\n\x3c/table\x3e\n\x3cdiv class=\"form-item\" id=\"edit-upload-wrapper\"\x3e\n \x3clabel for=\"edit-upload\"\x3eAdjunta un fitxer nou: \x3c/label\x3e\n \x3cinput type=\"file\" name=\"files[upload]\" class=\"form-file\" id=\"edit-upload\" size=\"40\" /\x3e\n\n \x3cdiv class=\"description\"\x3eLa mida m&agrave;xima d\'una pujada &eacute;s \x3cem\x3e1 MB\x3c/em\x3e.
