Warning: constant(): Couldn't find constant IH_RESIZE_TITLE in init_image_handler.php

[adb34]

I have just installed V1.5.6 with theme "Tableu2" with plugins, display logs, worldpay & encrypted_master_password-2.3.1. When I have logged to the back office I am told there is a new error. On inspection this file is 12 pages long. I have no idea what is on about and it is too big for here.

paste last 10 line of the log, maybe it can give us a clue of what is wrong, and we can help you in the right direction.

Actually, paste the lines associated with the first error in the log rather than the last... the problem starts up to and ends up leading to the last issue in the log.

Note that if you're experiencing a whitepage or partial whitepage type error, it will actually be the last entry in the log that's significant.

Note that if you're experiencing a whitepage or partial whitepage type error, it will actually be the last entry in the log that's significant.

How to word this... the error at the end of the list will identify where the last opportunity was to possibly precent the operation from succeeding, but it is because of the warnings that occurred before then that guide to how the bad data got to the end error.

For example, if a class was to be included for execution of an operation, but the class was not present, there would be a warning that the class file did not exist followed by an error at attempting to access a non-existent class.

Which was more "significant"?, the lack of the class or that the file in the include didn't exist? Yes, code could be added to verify the presence/absence of the class before attempting to use it just as before the use of each and every variable the existence could be determined. Time and place for such checks of course, but not an always/everywhere action.

That exposes that there are some Image-Handler-related defines that aren't registered properly. There are others in that log as well.

I haven't looked at the IH plugin to know whether the problem is in the plugin, or if it's because you haven't installed it properly. Perhaps someone using IH can help with that.

What I am going to do is do a fresh re-install and see what is happening and which plugin is causing some sort of problem with the v1.5.6 zencart. I am not in a rush to get this site running.

I don't know what version of IH is loaded, but the current version's (5.1.1+) /admin/init_includes/init_image_handler.php is only 295 lines long and those errors are showing up on lines 493 and 534.

i think a fresh install is required....

in the latest version (and again thanks to @lat9 for maintaining!) the constant referred to is in:

/YOUR_ADMIN/includes/languages/english/image_handler.php

it was moved from:

/YOUR_ADMIN/includes/languages/english/extra_definitions/bmz_image_handler.php

should be pretty easy to resolve this problem with a fresh install (which i think i need to do myself!)

best.
