  • Something happened between 2.4.1 and the first patch. I got the first patch installed by extracting it into my website's directory on the server. Then I could run the upgrade scripts. I i didn't think to turn on error reporting at the time. 

    So when I attempted to install patch 2 I turned on Error Reporting and Logging. I got the following error. 

    Fatal error: Uncaught Error: Call to undefined method Archive_Zip::setErrorHandling() in /home/bjk03/bjkline.biz/framework/modules/administration/controllers/administrationController.php:692 Stack trace: #0 /home/bjk03/bjkline.biz/framework/core/expFramework.php(456): administrationController->install_extension_confirm() #1 /home/bjk03/bjkline.biz/framework/core/subsystems/expTheme.php(796): renderAction(Array) #2 /home/bjk03/bjkline.biz/framework/core/subsystems/expTheme.php(910): expTheme::runAction() #3 /home/bjk03/bjkline.biz/themes/coolwatertheme/subthemes/Full Body.php(51): expTheme::main() #4 /home/bjk03/bjkline.biz/index.php(102): include('/home/bjk03/bjk...') #5 {main} thrown in /home/bjk03/bjkline.biz/framework/modules/administration/controllers/administrationController.php on line 692

    The server is running PHP 7.0.14. 
  • You did indeed catch an overlooked bug in the code since last Dec 16th...the two PEAR modules we've always included are not written the same...will be fixed for the next release, patch 3 out in a week or two.

    The work-around would be to convert the patch to a tar.gz or .tar.bz2 file and upload it.

    I don't think making the patch a tar.gz or tar.bz2 is the correct work-around. Here's how I attempted to make the .tar.gz. These steps were done on a Mac running OS X 10.11.6.

    First I downloaded the .zip file from the link in the first post of this topic. Then I extracted it. This created a exponent-2.4.1-patch-2 directory. Then I ran this command from the Terminal: tar czf exponent-2.4.1-patch-2.tar.gz exponent-2.4.1-patch-2

    I then tried to upload into Exponent. I went to the Admin menu -> Super Admin Tools -> Extensions -> Install Extension. Then I clicked on the Upload Extension tab. Then I choose the exponent-2.4.1-patch2.tar.gz file. I also checked the Patch Exponent or Install Theme box. Finally I clicked the Upload Extension button. The files appeared to copy over but I wasn't prompted to run the upgrade scripts. 

    This was on a server that's running php 7.0.14. I've got one site that is still using php 5.6.  I will try uploading the tar.gz version and see if that works.

    EDIT: Using php 5.6 makes no difference. I still don't get prompted to run the upgrade scripts.
