Thanks for the additional information! As I wrote, I am re-working this part of the MLA code and had already removed the offending line (60) in my Development Version. As you reported, it still exists in the current released version MLA 2.70.
The next MLA version will correct this issue. In the interim you are welcome to try the MLA Development Version. Note, however, that the Development Version supports ACP “export”, which may not be entirely stable. To get the Development Version, follow the instructions in this earlier topic:
504 Time-Out issue
Skip down to the “To get…” instructions. You can ignore the example plugin instructions.
If you do try the Development Version, let me know how it works for you. If you need a patch for the current MLA production version, let me know. I will leave this topic unresolved until the fix goes out in the next MLA version. Thanks again for your report and for your interest in the plugin.
